Kurt Vonnegut: Be soft. Do not let the world make you hard. Do not let the pain make you hate. Do not let the bitterness steal your sweetness. Take pride that even though the rest of the world may disagree, you still believe it to be a beautiful place.
My most favorite quote of ALL TIME by Tupac, should read ".or you can just leave the pieces on the floor and move THE FUCK on." explicit but rolls off the tongue better once you finally get to that point.
