Yet, I have to offer something here...that I know. At the moment I'm thinking of Jimmy Valvano's speech at the ESPY awards in 1993 or so. The guy is dying of cancer, yet he gives the most uplifting speech you can imagine. In it he says, among other things, that he tries to do three things every day. He says you should laugh every day. You should think every day. And every day you should have your emotions driven to tears, could be happiness or joy. And think about it...if you laugh every day, you think every day, and you cry every day...that's a pretty full day.
To me those are words worth living by.
