Live like there's no tomorrow,
Love like you've never been hurt,
Dance like nobody's watching,
and fuck like you're being filmed.

I actually like the words of Andy Capp, a cartoon strip in The Daily Mirror years ago, created by Reg Smythe, who said, amongst other gems "One half of the world is trying to have fun and the other half are trying to stop them."
