Before trades, write intent, base rates, alternatives, risks, and emotional state; after outcomes, grade only the process. Patterns emerge: rushed entries, narrative bias, or ignored stops. By auditing your mind on paper, you insulate capital from recurring impulses and build the kind of humble confidence volatility cannot counterfeit.
Imagine the decision failed spectacularly one year from now. List plausible causes, then invite a trusted skeptic to attack your thesis. Repair the weaknesses immediately. This rehearsed adversity sharpens analysis, reduces overconfidence, and transforms setbacks into rehearsals, so surprises bruise less and portfolios can bend without breaking.
Codify thresholds that trigger rebalancing between assets or factors, then execute on schedule regardless of headlines. This mechanical correction harvests volatility, sells relative winners, and adds to discounted positions without angst. Turn market swings into routine maintenance, like aligning tires, extending the journey by smoothing otherwise jarring detours.
