Choose other peoples' words wisely
So, on the outside walls of the cubes at work we have these little whiteboards for letting people know that we're on vacation or whatever. Most of the time they go unused, so some people have gone to putting inspirational quotes on theirs.
So I decided to put "It's an empty journey to triumph if you don't plant the seeds of catastrophe along the way." That didn't go over too well. I ended up switching to "If you can't beat them, arrange to have them beaten." That one's still up there.
