You made that choice with what you knew back then. Judge it by that version’s info, not today’s.

Hindsight rewrites decisions using information the decider did not have, and then judges them by it. That is not fairness, it is a trick of sequence, and it is the mechanism behind most of the harsh things people say about their younger selves. You were choosing in the dark with whatever light was available.

When an old decision comes up, reconstruct what you actually knew at the time. Judge it against that. There may still be a lesson in it, and there is much less reason for contempt than it first appears.
