Moving this from the PF by request:
I can't speak for everyone else, but yeah, I live my life in a constant state of anger/unhappiness. Sometimes I keep it suppressed, some times it boils over. What I've learned is to take an Epicurean approach, and minimize the opportunities for unpleasant activities in my life (he was not a hedonist, contrary to popular belief).
Sometimes limiting the unpleasantness means not reading or responding to particular individuals on the internet who also appear to live in a constant state of anger/unhappiness...or it means joking about their anger. I have found that people will be somewhat more reasonable if they don't take you seriously.
