One thing to keep in mind is this:
Wise people are often wrong.
Smart people make dumb mistakes all the time.
Diligent workers still don't get to approach every single problem with meticulous attention to detail.
Rational, reasonable people nonetheless inevitably hold some inconsistent beliefs.
... and so on.
You can be wrong without being bad.
It can be hard to remember this at an emotional level, especially if you have a history of being belittled for making mistakes, or you feel like you're not taken seriously enough. But it's true! Remind yourself of it. :)
