The simplest durable lesson here is this: a good outcome does not automatically validate a good process. Core idea: Markets occasionally reward sloppy reasoning. That is exactly why investors need post-trade review standards that do not depend only on P&L. Why it matters: If you only learn from outcome, luck gets promoted and discipline gets demoted. In real life: A rushed trade that works once can be more dangerous to your process than a thoughtful trade that loses within plan. Common slip: The mistake is using profit as the only teacher. Try this: Explain in one sentence what problem this idea solves and what problem it does not solve. That is usually where the edge is: not in the vocabulary, but in the structure underneath it.
