what motto would you mostly like as a bumber speaker?

I use to say "I have nothing to lose." :)

One of the ones that I like quite a bit is "Not all who wander are lost," which is from J.R.R. Tolkien. But I also have a bumper sticker that a friend bought me (not on my car, though), that says "Always take life with a grain of salt... and a slice of lime and a shot of tequila." I really like that one also! :)
