Well, in case anyone missed it, find it here or here, a wikipedia article about it here and the song that that was made out of it here
And here are my favorite bits from it:
Don't waste your time on jealousy.
Sometimes you're ahead, sometimes you're behind.
The race is long and, in the end, it's only with yourself
But go ahead and read the original. Its some of the best advise on the planet.
Maybe you'll marry, maybe you won't.
Maybe you'll have children, maybe you won't.
Maybe you'll divorce at 40, maybe you'll dance the funky chicken on your 75th wedding anniversary.
Whatever you do, don't congratulate yourself too much, or berate yourself either.
Your choices are half chance. So are everybody else's.
Accept certain inalienable truths: Prices will rise. Politicians will philander. You, too, will get old.
