Stop judging others so harshly it’s probably the #1 way. Whatever measure you use is going to be used on you. Step #2 is probably to listen fully to the end before ever speaking. This is hard, and took me a long time to get right. Just let them speak.
When receiving feedback, start by saying internally, or even verbally, I realize that I’ve made a mistake, and I’m thankful you have my best interests in mind and feel comfortable enough to approach me about it. I tried my best, but what did I not understand correctly about the problem I was supposed to solve, and what would have you done instead?

No, feedback is someone else's opinion - don't assume that it's absolutely correct, listen to it and weigh it up and then decide if you agree with any of it.
You have to be able to accept feedback without taking it personally, but you should always be objective about it.
