Financial theory
Use models as tools for thinking while respecting their assumptions and limits.
- Which assumption carries the result?
- Where does the model stop applying?
Make decisions that survive uncertainty
Strategy
Use financial theory, behavioral insight, risk analysis, and scenario planning to make choices that remain useful as conditions change.

Behavioral finance
Recognize bias, incentives, social pressure, and emotional patterns that change money behavior.
- What feeling is driving urgency?
- Which choice would be made without social proof?
Risk & uncertainty
Separate measurable risk, unknown outcomes, catastrophic downside, and recoverable mistakes.
- What can permanently impair the plan?
- What uncertainty can be tolerated?
Compounding & time
Understand how repetition, delay, rates, and persistence shape long-term outcomes.
- What repeats?
- What is the cost of waiting?
Opportunity cost
Measure what a commitment prevents, not only what it provides.
- What becomes unavailable?
- Is the trade reversible?
Expected value
Compare outcomes, probabilities, downside, and variance without hiding uncertainty inside one number.
- How sensitive is the estimate?
- Can the downside be survived?
Decision frameworks
Use repeatable questions, pre-mortems, checklists, and thresholds for difficult choices.
- What evidence would change the decision?
- What rule prevents impulsive action?
Financial independence
Define enough, optionality, work flexibility, and the systems that reduce forced choices.
- What freedom is being purchased?
- Which costs are permanent?
Scenario planning
Prepare for multiple plausible futures instead of optimizing for one forecast.
- What stays true across scenarios?
- Which option preserves flexibility?
A repeatable sequence
Decision lens
Use the same six questions to slow down high-impact choices and expose trade-offs.
- 01 Goal
State the outcome without naming the preferred solution.
- 02 Downside
Identify the largest plausible loss.
- 03 Reversibility
Know what can be undone and at what cost.
- 04 Opportunity cost
Name the option being displaced.
- 05 Expected outcome
Use ranges instead of false precision.
- 06 Time horizon
Match the decision to how long consequences last.

- Write the decision before researching products.
- Name the strongest reason not to proceed.
- Set a review date and a stop condition.
- Prefer options that preserve future choices when evidence is weak.
