Why do you get angry?

You get angry because something triggers adrenalin to be released, and too much makes you... rowdy. the best way to deal with this is to first identify what makes you angry, what you do when your angry, and how many minutes a day your angry, and focus on slowly raising your tolerance level, and finding new ways to deal with it. In a positive way that doesn't hurt anyone or yourself. If you keep doing this, you eventually will be able to be "The Nice Guy"
