Walk away from things that are over and past, just learn your lesson, over, done.
Again and again ask yourself "Why did I do that" and when the answer won’t come just say "So what!" it’s over and done.
Walk away from things that are over and past and cannot be undone. Reach forth to the things that are to come. Take your lesson, make yourself wiser, say "So what!" on past mistakes, forget them and go on. You didn’t find a solution. Before "So what!" the past is gone.
