Target Audience
Ideal Reader
- Investors who want better judgment under uncertainty (not stock tips)
- Anyone building a repeatable decision process: checklists, pre-mortems, and bias controls
- Business builders and allocators thinking about incentives, moats, and capital allocation
- People who enjoy dense, high-signal speeches and aphorisms
May Not Suit
- Readers who want a step-by-step valuation textbook (DCF/accounting heavy)
- Short-term traders looking for tactics, setups, or timing rules
- People who dislike philosophy/mental models and prefer purely quantitative playbooks
Investor Fit
| Strategy | Value Investing · Quality Investing · Behavioral Finance · Portfolio Management |
| Time Horizon | Long-term (5+ years) |
| Asset Focus | Equities · Multi-Asset |
| Math Level | Basic Arithmetic |
| Prerequisites | Basic understanding of stocks/businesses · Willingness to read slowly and take notes · Comfort with simple probability/expected value thinking |
Key Learnings
- 1Your edge is a better decision process, not better predictions
- 2Build a latticework of mental models across disciplines; single-model thinking breaks
- 3Invert problems: avoid failure modes first, then optimize
- 4Incentives are a master lever; misaligned incentives create predictable disasters
- 5Biases do not act alone; combinations can create lollapalooza outcomes (extremes)
- 6Prefer simple, robust reasoning to fragile precision
- 7Opportunity cost is real: every yes is a no to something better
- 8Spend your time on high-leverage decisions; avoid constant low-quality activity
- 9Patience + quality + discipline beats cleverness applied inconsistently
- 10Avoid leverage and fragility; survival is compounding prerequisite

Takeaway
Incentives + weak governance + complexity can produce systemic bad behavior and predictable blowups.
Investment practices of charitable foundations
Takeaway
Bad process and committee incentives can destroy long-term outcomes even with good intentions.
Academic economics vs real-world decision-making
Takeaway
Models are tools; when they ignore incentives, psychology, and second-order effects, they mislead.
Notable Quotes
“Spend each day trying to be a little wiser than you were when you woke up.”
“Invert, always invert.”
“Without numerical fluency you are like a one-legged man in an ass-kicking contest.”
Mental Models
- —Latticework of mental models (multi-discipline thinking)
- —Inversion (solve by avoiding what causes failure)
- —Incentives (follow the payoff function)
- —Second-order effects (what happens after what happens)
- —Base rates (start with reference classes before stories)
- —Circle of competence (know what you truly understand)
- —Opportunity cost (best alternative matters)
- —Compounding (small advantages + time)
- —Margin of safety (buffer against error and bad luck)
- —Checklist discipline (reduce avoidable stupidity)
- —Probabilistic thinking (ranges, not point estimates)
- —Lollapalooza effects (multiple forces reinforcing to extremes)

Limitations & Caveats
Keep in mind
- •Not a stock-picking cookbook; you must translate principles into your own process
- •Not a modern markets/ETF/tax implementation guide
- •Easy to collect mental models without changing behavior
- •Can be misused to justify overconfidence (I have many models so I must be right)
