i think journals are invaluable. I know mine, i write down every days something good that has happened to me. Even stuff like, 'i got to work safely, car didn't break down, lunch was delicious, i get to go to school,' ect. Simple things like that. After a short while, everything turns into something good.
With people that just get under my skin, i try to do something nice for them. Like go outta my way for them. Even if they don't appreciate me, i will have a new found respect for them.
I don't necessarily think anger will increase testosterone levels, but i understand you klosey. I think its more of an aggression thing, than an anger thing.
Being extremely aggressive from time to time is a big stress releiver. Makes me feel tons better, and keeps me sane
