Weight control does have to be for a lifetime or you'll be yo-yoing.
It doesn't matter what you achieve, if you don't keep growing you'll feel dead.
Live life fully while you're here. Experience everything. Take care of yourself and your friends. Have fun, be crazy, be weird.
The past does not equal the future.
You can't succeed by being good. That's what you get paid for. You can't succeed by being excellent. That's what you're expected to do. You can only succeed by being outstanding.
