When you ask „How was I?”, you are fishing for compliments.
It’s not easy for a polite person to tell you the truth.
A better question – „What would you do different, next time, if you were me?”.
Or: „How would you do it better next time?”.
Or: „What could I do better, next time?”.
Focus on the future, and start with the assumption you can improve, rather than asking for an overall picture.
