Sometime back in the later years of high school, I got tired of regretting certain things I’d done. By that point, I knew myself well enough that, if I just thought about what I was about to do, I’d know whether or not I would regret it later. And once a thing is, what good does regret do? I therefore adopted the motto: Don’t do anything you’ll regret, and don’t regret anything you do.
And I don’t regret a single stupid thing I’ve done since.
“Clean mind, clean body. Take yer pick.”

Illegitimus non carborundum. I like it better in Latin. If I got it wrong, I’m sure The Sausage Creature will correct me.
A very wise old dog once said to me, "If you can’t eat it or fuck it … piss on it.
