My only regrets involve holding on too long, believing that I was wanted when it was only that my existence merely fed a badly articulated need. The last year with the ex, the last month of contact with a once dear friend, when I should have simply been the bad guy and put an end to it. Sticking to theater instead of trying a different degree course when I never got cast.
Actually, I also regret committing too soon to a course of study when I had a full ride scholarship to college, instead of taking all kinds of classes and finding out what I would love.
