What's your life motto?
For example: Every cloud has a silver lining; What goes around comes around; Nothing ventured, nothing gained.
My personal motto is to do as you would be done by. It covers all manner of misdeeds and as long as you want to be treated well, you can't really go wrong with it.
I'm putting this to vote because I can't decide which answer is best and I'd like to see where the votes will fall :-)
