Oh long walks are great too, I normally prefer those walks alone..you know no music just a chill walk. I guess anger can be if it is matched with determination, otherwise it ends up being one of those self-destructive habits. I sometimes like messing with people, but normally I just watch lolzz. You'd be surprised when the coolest people just lose it.
Sometimes the best way to deal with anger is right in front of a punching bag lolz...very therapeutic.
