Breaking the rules is like cheating—only zero times or infinite times.

The gap between knowing and doing is vast.

You get stopped out on one trade and lose $50,000, versus getting stopped out ten times in a row, losing $5,000 each time—which feels worse? The latter is far more painful. The amount is the same, but being defeated ten times in a row creates frustration that can strip away your rationality, even your courage, dragging you into self-doubt and making it hard to continue.

The great Way is smooth, yet people prefer shortcuts. The path identified by algorithm as the long-term winning strategy is precisely the one you can't bring yourself to follow.
