You know that moment? You nail the timing, take profits at 2x, close the position feeling pretty good—then watch it pump another 50% without you. Made the money, ticked the win box, yet somehow it still stings. That FOMO kicks in hard. But here's the thing: locking in gains is locking in gains. Nobody ever went broke taking profits early. Sure, the "what if" can mess with your head, but consistent exits beat chasing every moonshot. The market always has another opportunity waiting. Discipline beats regret.
