Your Own Worst Enemy
No terminal, no numbers to crunch — just you, living through one full market cycle: a calm melt-up, a mania, a crash, a recovery. At each turn your own mind hands you an impulse — the move that feels obviously right and is quietly wrong. A disciplined 'plan' investor rides the cycle without flinching; every time you act on a feeling, your path diverges from theirs, and that gap is the whole game. The right move almost always feels wrong: do nothing while everyone's getting rich, hold while your portfolio halves, buy back the day after you swore off stocks. Notice the feeling. Overrule it. Every bias of the course, one cycle.
The market can't hurt you. You can. Ten moments, one enemy — the one making the decisions.
