Principles
Repeatable rules that beginners can study and adapt.
Applicable principles
You do not need to be right all the time; size up when the opportunity is clear.
Assess liquidity and monetary policy before major bets.
Cut positions when the thesis weakens.
Seek asymmetric payoff, not only a high win rate.
Turn these principles into a pre-investment checklist. If an idea cannot pass the checklist, staying out is often better than forcing action.
