The old you wasn’t stupid. They were just working with less information. Give them some credit.

Looking back at a decision with everything you now know makes the right answer obvious, which makes whoever chose wrong look foolish. They were not. They had a smaller map and were doing their best inside it, and you would have made the same call standing where they stood. Hindsight is a poor judge because it shows up with the answers already printed.

Take one decision you keep rerunning and list what you did not know at the time. Say the list out loud. Then judge the choice against that map instead of this one.
