The trick is channeling the anger into worthwhile pursuits and not letting that anger get the best of you.
Being able to control your anger is what men do. It is childish to show your anger constantly. It is childish to not be able to control your anger, or to show your anger inappropriately. Certainly, your anger must come out at the right time – but each time some little thing bothers you is not the right time to show your anger. This is not repression, it is channeling. The anger must be channeled into a higher pursuit.
