How to deal with performance anxiety at work?

Increase your self esteem. Lots of good reads out there, in self help books .
Power of positive thinking 👍

1. Always work on improving yourself.
2. Give your best.
3. Be mentally prepared to give resignation any time.

Just imagine others as naked, on the toilet, etc. to make them seem more human. Ask questions, learn with humility, speak up if you know something not yet discussed, etc.

You were hired for your position for a reason.

Me, too.

its common so be easy on yourself.
