In your head don’t spend time going over how you could have done things better/differently. Initial evaluation is good when things could have gone better, but past a certain point you’re just beating yourself up and getting worse than nothing out of it.

If you beat yourself up mentally to much, it’ll make it harder to do anything, because you’ll be afraid of failure etc.

That’s partially how I think of it anyways.

Also, be realistic with your expectations.
