The proactive thing to do, naturally, is to try to minimize how many mistakes you make.

I think you came close to saying the proactive thing to do just after this. You talked about correcting mistakes. One step behind that is not repeating mistakes. One step behind that is identifying mistakes. Mistakes unseen will be repeated. Identified mistakes might not be repeated, even if they cannot (at the time) be corrected.

Your model builds up your confidence and skills so keep it up! Part of that process is calving off parts of the mistake iceberg, never to be repeated again.
