What was a change that you made to your life because you were bullied?

I changed my attitude. I was bullied in Elementary school until I decided to take matters into my own hands and put an end to it. There was a kid who bullied me and would push my face and push my buttons as much as he possibly could. One day I found him playing with a ball by himself in a hidden corner of the school. I went up behind him and took the back of his head with my right hand and smashed it up against the brick wall of the school while gritting my teeth and making a demonic looking face until the front of his face looked like uncooked ground beef. He bled so profusely from his forehead that he couldn't see out of his eyes. No one was ever able to prove that I did it.
