What I've Learned So Far

February 12, 2026

Key Narrative

At 36, I’m roughly halfway through my working years and likely a third of the way through life. This is a pause to take stock: what have I learned that I didn’t know at 25? What inputs actually drive my output and happiness? And what should I prioritize in the decades ahead?

This isn’t advice—it’s an attempt at honest self-assessment. What works for me may not generalize. But the exercise of articulating it is clarifying.


Outline

I. Introduction


II. Things I’ve Learned

A. On Work

  1. Compounding is everything

    • Skills, relationships, reputation—all compound
    • The implication: patience and consistency beat intensity
  2. The importance of the work matters more than the quality

    • Direction over velocity
    • Choosing problems > solving problems
  3. Management is a distinct skill, not a promotion

    • I had to learn this the hard way
    • The transition from doing to enabling
  4. Speed is underrated

    • Fast iteration beats careful planning
    • But: fast on execution, slow on strategy
  5. Most business problems are people problems

    • Hiring, culture, incentives
    • Technical problems are often easier

B. On Thinking

  1. Writing clarifies thought

    • If you can’t write it clearly, you don’t understand it
    • The discipline of the page
  2. Strong opinions, loosely held—actually practiced

    • Conviction to act + humility to update
  3. Mental models accumulate

    • Reading across disciplines pays off slowly, then suddenly
    • The value of history, physics, biology as lenses
  4. Intuition is compressed experience

    • Trust it more as you get older
    • But keep calibrating it

C. On Relationships

  1. A few deep relationships beat many shallow ones

    • The returns to depth are convex
  2. Marriage is a choice you make repeatedly

    • The decision to marry is just the first one
  3. Proximity drives relationships

    • Invest in being near the people who matter
    • This is underrated in career decisions
  4. Most conflicts are misunderstandings

    • Steel-manning prevents most arguments
    • Assume good faith until proven otherwise

D. On Health and Energy

  1. Sleep is the foundation

    • Everything degrades without it
    • Protecting sleep is a productivity strategy
  2. Exercise is non-negotiable

    • The cognitive benefits rival the physical ones
  3. Energy management > time management

    • Know your peaks and protect them

E. On Happiness

  1. Adaptation is powerful—both directions

    • Hedonic treadmill applies to gains and losses
    • Implication: focus on process, not outcomes
  2. Meaning comes from difficulty

    • Comfortable lives are not necessarily good lives
    • The value of challenges chosen
  3. Gratitude is a practice, not a feeling

    • It can be cultivated deliberately

III. My Personal Production Function

IV. Priorities Going Forward

A. Doubling Down

  1. Health: More aggressive about sleep, exercise, diet
  2. Family: Time with children while they’re young
  3. Deep work: Protect mornings more ruthlessly
  4. Writing: Increase output, develop voice

B. Adding

  1. Community: Invest in local relationships
  2. Teaching: Give back accumulated knowledge
  3. Creative pursuits: Music, specifically

C. Reducing

  1. News consumption: Low information, high anxiety
  2. Performative obligations: Say no more often
  3. Optimization: Accept good enough

D. The Big Questions
