In some way I can understand if you want to burn some brigdes behind you, but I think burning all of them is almost mission impossible. Your past will catch up on you sooner or later. Especially if you have unfinished issues. But what I don´t understand is that you burn bridges in front of you. In my opinion, that is the most stupid thing a person can do. I am watching from a side as one person I know is doing exactly that. In the future, he will regret that. I´m sure of it.
