The fear of missing out (FOMO) is not a personality flaw, but a symptom of undefined entry conditions.
Behavioral Finance Explanation
When "loss aversion" combines with "social proof" (safety in numbers), we easily get swept up in market frenzy. The fix is structural: write your entry criteria on paper, and define "skipping" as the correct action if conditions aren't met. Entries outside your plan empirically trend toward negative expected value long-term.
Practical Approach
Iron rule: "No entry without a reason." A rally after you skip is an event outside your system's scope, and requires zero regret.
