"Life, if you know how to use it, is long" - Seneca, "On the Shortness of Life"
Or for a more modern twist on this sentiment:
"You gotta play it how it go, you can't cheat on life.
Ya better drink a Red Bull, you can't sleep on life."
-- Young Jeezy, "I Luv it"
An inaugural poem of protest by Robert Pinsky
