Every path you didn’t take still taught you something about the one you’re on.

Choosing one thing means not choosing several others, and those unchosen options are not simply wasted. Finding out you did not want the other course, the other team, the other town is real information, and it is usually what tells you why the current path fits. Regret likes to present the alternatives as unexamined. You did examine them, which is how they got ruled out.

List two things you decided against and write the reason beside each. If the reason still holds, the decision is doing its job and the second-guessing can stop.
