My dad told me some time ago, "Where you stand today is the end result of every choice you have ever made. Sounds complicated? It's not."
If your life sucks, it most likely sucks because your choices have sucked. If your life is great, it's most likely great because your choices have led it to be great.
So when the drugged out Marxist hippies in the Flea Party scream about how life is so unfair, just remember - their lives suck because of the choices they have made.
