Don’t take criticism personally – even if you think it’s unfair. Trust me, I understand that this can be easier said than done, especially if you’re hurt in the process.
DON’T GO THERE.
Instead remind yourself you’re stronger than them, think clearly about what’s best for the greater good, and hold your head up. Once you’ve cooled off, think clearly about the criticism – maybe you can learn something from it, maybe not. Approach your analysis as an opportunity to grow. Then move on. Don’t perseverate.
If you feel like you’re being bullied, aggressively and forcefully ask for clarification. Don’t back down – look them in the eye and try to get a handle on whatever the issue is. You have to face this head on while remaining in control, but whatever you do don’t allow yourself to get emotional. It’s going to get uncomfortable and that’s ok – by confronting the bully you are going to make them uncomfortable too, and they won’t like it. Even better, do this in front of other people.
Don’t ever respond when you are angry. You will regret it. If you feel yourself becoming angry, just don’t say anything. Respond only when you can do so calmly. Remember that you are the one in control.
Ultimately try to be an agent for good. If I’m feeling down or out of sorts, I think “What can I do for someone else?” and soon I’m feeling better.
And finally, don’t hold grudges.
You’re a better person than that.
