Fix it and Move on!

I'm still reading 'Principles' by Ray Dalio (among others ;) )

"Imagine how silly and unproductive it would be to respond to your ski instructor as if he were blaming you when he told you that you fell because you didn't shift your weight properly.

IT'S NOT DIFFERENT IF A SUPERVISOR POINTS OUT A FLAW IN YOUR WORK PROCESS.
FIX IT AND MOVE ON!

Put your insecurities away and get on with achieving your goals.
An accurate criticism is the most valuable feedback you can receive."
