Hedonic Adaptation

This refers to the human tendency to quickly return to a relatively stable level of happiness despite major positive or negative events. We adapt to new circumstances, causing the initial emotional impact to fade over time, requiring us to constantly seek new achievements for fleeting satisfaction.

Negative Visualization

An ancient Stoic technique where one imagines losing everything they value (e.g., spouse, job, health). This practice resets reference points, helps combat hedonic adaptation, and fosters a deeper appreciation for current blessings by making their absence salient.

To Me vs. By Me Leadership

The 'to me' mindset views external circumstances as the cause of one's experience, leading to a victim mentality. The 'by me' mindset recognizes that one is the creator of their own emotional, physical, and mental states, taking 100% responsibility for their experience regardless of external events.

Drama Triangle

A psychological model describing three reactive roles people adopt in conflict: Victim (disempowered, less than 100% responsibility), Villain (blames self or others), and Hero (seeks temporary relief without addressing core issues). These roles perpetuate drama and prevent genuine resolution.

Go vs. No-Go Functions

These are two main circuits in the basal ganglia, regulated by dopamine, that control thought and action. 'Go functions' are action-oriented (e.g., picking up a phone), while 'no-go functions' involve suppressing behavior (e.g., sitting still, delaying gratification). Training both is crucial for impulse control and effective action.

OODA Loop

An acronym for Observe, Orient, Decide, Act. It's a framework for rapid decision-making, originating from fighter pilot terminology, emphasizing the importance of quickly cycling through these stages to gain an advantage, especially in fast-changing environments like technology.

Chronotype

This refers to an individual's natural inclination to sleep at a certain time, categorizing people as morning types (larks), evening types (owls), or neutrals. It reflects where the peak and trough of an individual's unwavering 24-hour circadian rhythm naturally reside on the clock face, influencing ideal sleep and wake times.

Epigenome

The control system that tells cells which genes to turn on and off, determining how a cell behaves (e.g., nerve cell vs. skin cell). Aging is proposed to be the breakdown of this epigenomic information, leading to tissue dysfunction and disease.

Sirtuins

A set of seven genes that make proteins controlling the epigenome. They help bundle up genes that should be switched off, preventing them from activating in the wrong cells. Activating sirtuins through methods like adversity (e.g., fasting) can slow down the aging process and improve health.

?
What evidence-based strategies can increase happiness?

Happiness can be significantly improved by increasing social connection, doing nice things for others, focusing on healthier habits like sleep and exercise, and practicing gratitude, such as writing down 3-5 things you're grateful for or expressing gratitude to others.

?
How does genetics influence happiness, and can parents influence their children's happiness?

Happiness is heritable, with estimates around 30-40%, but genetics is not destiny. Parents can significantly influence their children's happiness by modeling positive behaviors, building in happiness-boosting strategies early on, and managing their own emotional states, as emotions are contagious.

?
What parenting techniques, though well-intentioned, can lead to unhappiness or anxiety in children?

Over-intervening parenting styles, like 'lawnmower' or 'steamroller' parenting, where parents preemptively solve problems for kids, deprive children of opportunities to fail and learn. This can lead to kids developing beliefs that they are less capable, contributing to anxiety and a lack of resilience.

?
What are the key principles for creating a 'culture of love by design' in an organization?

The principles include putting people first (appreciating talent), including everyone (all stakeholders), uniting around a compelling vision and comprehensive strategy, having clear performance goals with one plan, relying on facts and data, expecting and dealing with reality, and fostering positive behaviors and emotional resilience while having fun.

?
What are the three essential components for a great life, beyond money or status?

Assuming good health, a middle-class income, and great relationships, a great life requires alignment between your aspirations (reason for existence), ambitions (achievements), and day-to-day activities. Overweighting ambition and achievement, however, can be a 'fool's game' as satisfaction is fleeting and outcomes are not fully controlled.

?
How can one avoid the 'drama triangle' and move from reacting to responding?

To avoid the drama triangle (Victim, Villain, Hero roles), one must take 100% responsibility for their own feelings and experiences ('by me' leadership), rather than blaming others or seeking temporary relief. This requires pausing, becoming aware, and being honest about what's happening, even if it brings discomfort or vulnerability.

?
How can individuals improve their impulse control?

Impulse control can be improved by deliberately practicing 'no-go' functions throughout the day, even with trivial actions like delaying picking up a phone or a bite of food. This reinforces the neural circuitry for suppressing behavior, which generalizes to other areas of life and helps counter the modern emphasis on 'go' functions.

?
What are Reid Hoffman's three principles for making faster and better decisions?

Hoffman's three principles are speed, simplicity, and empowerment. Speed means generally making decisions faster unless more time significantly improves the outcome; simplicity means using plans that can easily spread without distortion; and empowerment involves distributing decision-making within the organization.

?
What are some key lenses or frameworks for evaluating investment opportunities or business ideas?

Effective evaluation involves assessing if founders can explain their idea simply without jargon, if the product's value can be distilled into a transmissible message, understanding the real emotional motivations behind why people would use/buy it, envisioning how it scales to a large market, avoiding 'Swiss knife' over-engineering, and identifying a non-obvious but actionable insight.

?
What are the core human motivations that transcend culture?

The core human motivations revolve around constantly improving social status, which in turn improves mating success or the success of one's progeny. These motivations manifest differently across cultures (e.g., individualism vs. collectivism), but fundamentally drive desires for things like health, intelligence, and appearance, for which people would sacrifice significant wealth.

?
What factors almost guarantee a bad night of sleep?

Consuming stimulants like caffeine, alcohol, and nicotine will disrupt sleep. High levels of mental stress or anxiety also make it difficult to fall and stay asleep. Additionally, a mismatch between one's natural chronotype (morning/evening person) and their bedtime schedule, or spending too much time awake in bed, can guarantee poor sleep.

?
How does the aging process occur at a biological level?

Aging is increasingly understood as a loss of epigenetic information, which is the control system telling cells which genes to turn on and off. This breakdown in cellular instructions, analogous to scratches on a DVD, leads to tissue dysfunction, diseases, and the visible signs of aging.

?
How can controlled fasting help slow down or reverse aging?

Controlled fasting mimics adversity, activating sirtuin genes that act as epigenetic regulators. These sirtuins help maintain the proper gene expression by keeping unnecessary genes switched off. This process slows down the clock of epigenetic changes, leading to health benefits and potentially longer life by defending the body against damage.

?
How can a life-threatening health diagnosis change one's perspective on life and work?

A health diagnosis can provide profound gratitude for simple things, clarify purpose, and help put 'little deals' (minor anxieties) into perspective against the 'big deal' of survival. Professionally, it can sharpen focus on what truly brings joy and energy, leading to a re-evaluation of priorities and a conscious effort to balance work and personal life.

1. Don’t Condition Value on Achievement

Never base your self-worth as a human being on the results of your achievements, as outcomes are often uncontrollable and the satisfaction derived from them is temporary. Instead, focus on loving the process of what you do and connecting it to a higher purpose.

2. Adopt a ‘By Me’ Mindset

Recognize that your emotional, physical, and mental states are happening ‘by you,’ making you the creator of your own experience rather than a victim of external circumstances. This empowers you to take 100% responsibility for your well-being and responses.

3. Prioritize What Truly Matters

Regularly reflect on what you would drop or regret not doing if you only had a limited time (e.g., five years) to live. This mental exercise helps clarify your purpose and encourages you to prioritize activities that bring joy and align with your core values daily.

4. Align Life’s Core Elements

Ensure your aspirations (your reason for existence), ambitions (your achievements), and day-to-day activities are in harmony. The degree to which these three elements are aligned significantly contributes to having a great and fulfilling life.

5. Identify Core Human Motivations

Understand the deep-seated, universal drivers that compel human behavior, such as improving social status, mating success, or health, by asking what people would give half their net worth for. This insight allows you to effectively ‘press the motivation button’ in people, whether in business or personal interactions.

6. Seek Non-Obvious, Actionable Insights

Actively look for truths that are not immediately apparent but become clear and logical once revealed, as these are the smallest units of actionable truth. Operating in the currency of such insights is a hallmark of successful individuals and businesses.

7. Practice Negative Visualization

Start each day by briefly imagining that everything you value in life is gone. This ancient Stoic technique resets your reference points, combats hedonic adaptation, and fosters a deeper appreciation for the good things you currently possess.

8. Practice Daily ‘No-Go’ Functions

Deliberately introduce 20-30 small acts of suppressing impulsive behaviors throughout your day, such as delaying picking up your phone. This reinforces generic neural circuits for impulse control, which translates to better self-discipline in various aspects of life.

9. Make Decisions Faster

Generally, making a decision faster is better, especially in rapidly evolving environments. When faced with a major decision, determine what your choice would be if you had to decide immediately, then identify only the critical information or conversations that might genuinely alter that decision before proceeding.

10. Activate Sirtuins (Mimic Adversity)

Engage in practices that mimic perceived adversity, such as skipping meals, eating less protein, or experiencing hot and cold temperatures. These actions activate sirtuin genes, which are epigenetic regulators that slow down the aging clock and improve the body’s defense against damage.

11. Practice Gratitude (Writing)

Dedicate time to write down three to five things you are grateful for, as this simple act can significantly improve your well-being in as little as two weeks. Regularly counting your blessings enhances positive emotions and life satisfaction.

12. Parenting: Prioritize Own Happiness

Focus on your own happiness and well-being first, as children naturally catch their parents’ emotions through emotional contagion. By embodying calmness, gratitude, and a better emotional state, you implicitly transmit these positive traits and strategies to your kids.

13. Include All Stakeholders

Ensure that all relevant parties, including employees, suppliers, customers, and investors, are represented and have their voices heard in leadership and decision-making processes. This comprehensive inclusion leads to more robust strategies, plans, and objective accomplishment.

14. Compelling Vision & Relentless Plan

Establish a clear, meaningful, and purposeful vision for your organization, supported by a comprehensive strategy and a relentless implementation plan. This approach ensures all participants are aligned and dedicated to achieving shared objectives.

15. Distill Ideas to Simple Messages

Test the clarity of your ideas by trying to explain them without jargon, as if you were telling a friend over dinner. If an idea cannot be distilled into a simple, transmissible message, it will struggle to spread and incur high customer acquisition costs.

16. Manage Mental Health

Actively work to reduce stress and anxiety in your life, as these states can almost guarantee a bad night of sleep. Addressing mental well-being is crucial for improving sleep quality and overall health.

17. Develop a Wind-Down Routine

Create and consistently follow a pre-bedtime routine, similar to what children have, to help your mind and body transition from wakefulness to sleep. This could include a bath, meditation, light stretching, or listening to a sleep story.

18. Practice Intermittent Fasting

Incorporate fasting periods of at least 14 hours into your routine to gain health benefits such as better metabolic stability, lower blood sugar levels, and improved cholesterol. A common approach is the 16:8 method, skipping one meal a day.

19. Focus on the Immediate Task

When faced with distractions or past mistakes, let go of what you cannot control and concentrate solely on the present task or ’the shot in front of you.’ This approach helps maintain focus and prevents rumination from hindering performance.

20. Forgive Others and Yourself

Release the burden of wishing others were different or blaming them for your unhappiness. Forgiving others for being themselves and yourself for wishing they were otherwise prevents self-inflicted misery and allows you to move forward.

21. Avoid the Drama Triangle

Recognize and disengage from the roles of Victim (disempowered), Villain (blaming), and Hero (seeking temporary relief) in your relationships and problem-solving. These roles perpetuate reactive patterns and prevent addressing core issues.

22. Source Approval Internally

Cultivate self-approval and security from within yourself rather than seeking it externally. Relying on external validation leads to suffering and a constant need to control others’ perceptions of you.

23. Reinforce ‘Go’ Functions Early

Start your day by immediately engaging in action, such as making your bed, without rumination or overthinking. This sets your nervous system into an action-oriented ‘go’ mode, building momentum for the rest of your day.

24. Create Simple Plans

Design plans that are straightforward and easy to understand, as simplicity allows for widespread adoption without distortion throughout an organization. Err on the side of being overly simple for better scalability and application.

25. Be an Explicit Learner

Strive to learn new concepts in a way that allows you to clearly explain them to others as a tool or principle. This deepens your understanding and enhances your ability to apply and share knowledge effectively.

26. Identify Emotional Product Benefits

When developing or pitching a product, look beyond its functional utility to understand the deeper emotional motivations that drive people to use or buy it. Successful founders know both the functional and emotional benefits of their offerings.

27. Avoid the ‘Swiss Knife Problem’

Resist the urge to build a product with too many features from the outset when consumers are only looking for a core solution. Instead, focus on a clear ‘foot in the door’ strategy by offering a simple, essential product first, then expanding its capabilities.

28. Understand Willingness to Pay

Realistically assess whether your target users (e.g., parents, CFOs, kids) would genuinely pay for your product or service. Many ideas fail because founders overestimate the perceived value and willingness to pay.

29. Boil Wisdom to Core Units

Distill complex wisdom or ideas into their fundamental, indivisible components (first principles). This creates powerful building blocks for understanding and innovation, especially in business.

30. Avoid Sleep Disruptors

Refrain from consuming caffeine, alcohol, and nicotine, especially before bed, as these substances are stimulants and clear disruptors that will guarantee a bad night of sleep.

31. Align Bedtime with Chronotype

Determine your natural morningness or eveningness (chronotype) using a questionnaire like MEQ, and try to align your bedtime with your body’s innate urge to sleep. Mismatching your bedtime with your chronotype can lead to difficulty falling asleep.

32. Maintain Sleep Routine After Bad Night

If you experience a bad night of sleep, avoid compensatory behaviors like sleeping in later, going to bed earlier, napping during the day, or increasing caffeine intake. Sticking to your regular schedule prevents further disruption of your sleep cycle.

33. Take a Mental Journey for Sleep

Instead of counting sheep, which can prolong sleep onset, take yourself on a mental journey by visualizing a familiar walk, hike, or activity. This technique distracts your mind from ruminating thoughts and helps you fall asleep faster.

34. Remove Clocks from Bedroom

Eliminate visible clock faces from your bedroom to prevent anxiety and rumination if you wake up during the night. Knowing the time does not help you sleep; it only makes matters worse.

35. Eat a Mediterranean-Type Diet

Incorporate healthy foods typical of a Mediterranean diet, such as olive oil and red wine, into your eating habits. These foods contain chemicals that activate sirtuins, improving health and potentially slowing the aging process.

36. Focus on Eating Window

Prioritize when you eat over what you eat by consuming all your daily food within a short, consistent window (e.g., one hour). Animal studies show this can dramatically extend lifespan and improve health, even if total calories remain similar.

37. Cultivate Gratitude for Simple Things

Develop a deep appreciation for the everyday, simple aspects of life. This perspective shift, often gained after challenging experiences, enhances overall happiness and contentment.

38. Distinguish ‘Big’ from ‘Little’ Deals

Learn to categorize life’s challenges into ‘big deals’ (major, impactful events) and ’little deals’ (minor inconveniences). This reframing helps reduce anxiety over small issues by putting them into a broader perspective.

39. Give Permission to Lean In/Out

Consciously grant yourself permission to fully engage in work when desired and to disengage when personal time is needed, especially in flexible work environments. This fosters a healthier balance and prevents burnout.

40. Practice Evening Reflection

End your day with a brief reflection by asking yourself: ‘What am I blocking? What am I advancing? How did I make people feel?’ Answering these questions provides clarity and allows you to transition intentionally into personal time.

41. Increase Social Connection

Actively seek opportunities to enhance your social connections, as empirical psychology shows a direct link between strong social bonds and increased happiness.

42. Do Nice Things for Others

Regularly engage in acts of kindness for others, as contributing positively to others’ lives is a proven way to boost your own happiness.

43. Focus on Healthier Habits

Prioritize and actively work on improving your health habits, such as getting better sleep and more exercise. These foundational practices significantly contribute to overall well-being and happiness.

44. Express Gratitude to Others

Write a detailed thank-you note to someone you’ve always wanted to thank but haven’t. This act can significantly improve your well-being immediately and for over a month.

45. Reset Your Reference Points

Consciously shift your perspective to appreciate your current situation, especially during challenging times. Remind yourself that many others would gladly trade their problems for yours, leading to a broader and more positive outlook.

46. Parenting: Promote Early Happiness Skills

Introduce evidence-based happiness strategies and skills to children at a young age. This proactive approach helps them build a foundation for long-term well-being.

47. Parenting: Avoid Over-Intervention

Refrain from ’lawnmower’ or ‘steamroller’ parenting, where you preemptively remove all obstacles for your children. Allowing kids to fail and solve problems themselves is crucial for developing competence, resilience, and reducing anxiety.

48. Parenting: Model Calmness

Be mindful of your own emotional state, as children are highly susceptible to emotional contagion. By embodying calm and confidence, you help your children feel more secure and less anxious about challenges.

49. People First (Leadership)

Prioritize appreciating, thanking, and including all individuals involved in a project or organization. Recognizing their talent and humanity fosters a culture of ’love by design’ and motivates participation.

50. Clear Goals & One Plan

Ensure that your organization operates with clear performance goals and a single, unified plan. This eliminates confusion and ensures everyone is working towards the same objectives, unlike companies with multiple, conflicting plans.

51. Use Facts and Data (Leadership)

Base conclusions and decisions on concrete facts and data, not just opinions. This approach enables collective problem-solving and helps the team effectively address issues and turn ‘reds to yellows to greens.’

52. Share Reality (Leadership)

Regularly communicate the true status of the situation, including both opportunities and issues, with all stakeholders. This transparency builds respect and allows everyone to understand areas needing special attention.

53. Cultivate Emotional Resilience

Recognize that creative and innovative processes will inevitably encounter issues, and trust the established process for working together to resolve them. This mindset helps teams navigate challenges without getting discouraged.

54. Have Fun (Leadership)

Actively foster an environment where participants can enjoy the journey and each other while working towards shared goals. This promotes a positive and engaging culture.

55. Zero Tolerance for Violations

Establish and enforce zero tolerance for violations of the agreed-upon operating processes and expected behaviors. This ensures commitment, seriousness, and accountability across the team.

56. Address Core Issues

Instead of repeatedly seeking temporary relief for problems, take the time to identify and address the underlying core issues. This prevents recycling patterns of reactivity and leads to lasting solutions.

57. Pause and Become Aware

When faced with a situation, consciously pause to become more aware of what is happening rather than reacting compulsively. This allows for reasoned responses and avoids perpetuating drama.

58. Let Go of Being Right

Challenge your ego’s need to always be right, as this often serves as a defense mechanism to protect underlying vulnerability and fear. Embracing ‘I don’t know’ opens the door to growth and connection.

59. Stick to a Plan (Self-Discipline)

When you have a set plan, such as a gym routine, resist the impulse to spontaneously change it. Enforcing regimented adherence to your plan strengthens self-discipline and prevents defaulting to less effective actions.

60. Practice Focused Work Bouts

Schedule and commit to 90-minute periods of focused work, resisting the temptation to get up or switch contexts even when attention drifts. This trains tunnel vision and improves concentration.

61. Engage in ‘Hour of Pain’

Periodically undertake a low-cost, uncomfortable challenge, such as sitting in an awkward position for an hour, to deliberately build up your ’no-go’ circuits. This enhances mental toughness and the ability to suppress unwanted actions.

62. Practice ‘What If I Decided Now?’

Make it a ritual to consider what your decision would be if you had to make it immediately, without further information. This trains you to overcome the discomfort of quick decisions and identify truly essential data.

63. Evaluate Decision Recoverability

Before making a decision, assess whether it is a ‘one-way door’ (irreversible and catastrophic) or a ’two-way door’ (recoverable). This helps determine the appropriate level of certainty and evidence required.

64. Experiment with Decisions

Where possible, approach decisions with an experimental mindset, testing aspects of the decision or trying it out on a smaller scale. This reduces risk and provides valuable learning before full commitment.

65. Avoid Decision Biases

Be aware of common cognitive biases like sunk cost bias and blind spots, and actively work to mitigate their influence on your decision-making. This improves the quality and objectivity of your choices.

66. Test Understanding (Language/Level)

When evaluating someone’s understanding of an idea, ask them to explain it in a different language or at a different level of detail. Those who truly grasp the concept can adapt their explanation effortlessly.

67. Imagine Scaling from the Start

When developing a product or business, envision from the beginning how it could grow into a very large entity. This forward-thinking approach helps avoid getting stuck in a limited scope.

68. Consider 16:8 Fasting

A specific intermittent fasting protocol involves fasting for 16 hours and eating within an 8-hour window, often by skipping one meal like breakfast or a late dinner. This is a popular and effective way to achieve fasting benefits.

69. Consider Longer Fasts (Occasionally)

Explore longer fasts of 3-7 days a few times a year to trigger autophagy, a beneficial cellular recycling process. However, ensure adequate nutrition and consult professionals, as this is an extreme measure.

70. Avoid Spending Too Much Time in Bed Awake

If you’re struggling with sleep, avoid spending excessive time in bed while awake, as this can paradoxically worsen sleep. Your brain may begin to associate the bed with wakefulness rather than rest.

If I was like, you know, there's like this pill that you can take that will improve your well-being significantly for over a month, you take one pill and months later you're feeling good, you'd be like, man, I'm gonna do that. Like the simple act of writing a thank you letter can do that.

Laurie Santos

Never make your value as a human being conditioned on the results of what you're trying to achieve. Never do that. It's a fool's game.

Marshall Goldsmith

Happiness and achievement are independent variables. You can achieve a lot and be happy, you achieve a lot and be miserable, you achieve nothing and be happy, you achieve nothing and be miserable. Through independent variables.

Safi Bahcall (quoted by Marshall Goldsmith)

The smallest unit of truth that is actionable.

Kunal Shah

There's something weird that happens to our thoughts in the darkness of night. Our thoughts are not our own at night, they are darker just like the the absence of light around us, they the bad things feel twice as bad, the frightening things feel twice as frightening, the anxious things twice as anxious.

Matthew Walker

What if you have five years? What would you do differently? You do a lot more changing on the margin and the reality is we should all be thinking that way every day.

Sarah Jones Simmer

Post-Bad Night of Sleep Recovery

Matthew Walker
  1. Do not wake up any later than natural to 'sleep it off'.
  2. Do not go to bed any earlier than your normal time.
  3. Do not nap during the day to compensate.
  4. Do not drink more caffeine to get through the day.

Wind-Down Routine for Sleep

Matthew Walker
  1. Create a consistent routine to transition from wakefulness to sleep.
  2. Engage in calming activities like a bath/shower, meditation, light stretching, or being read to (e.g., sleep stories).
  3. Disconnect from stimulating activities and allow your mind to unwind.

Mental Journey for Falling Asleep

Matthew Walker
  1. Instead of counting sheep, take yourself on a mental journey.
  2. Visualize a familiar and pleasant experience, such as a walk, hike, or bike ride.
  3. Focus on the details of the journey, like what gear you'd be in or braking distances, to distract your mind from rumination.

Bedroom Environment for Improved Sleep

Matthew Walker
  1. Remove all clock faces from your bedroom.
  2. If an alarm clock is necessary, ensure you cannot see the time during the night.
  3. Avoid checking the time if you wake up, as knowing the time can worsen anxiety and make it harder to fall back asleep.
