The secret to living a full life with no regrets and to staying young is to figure out what you believe in and fight for it. If you lose, don't give up. If you win, raise the bar, and then rare back and do something else. And remember that, with the accumulation of years, our responsibilities to the future grow greater, not less.

Even when I wasn't sure where I was going, I was always in a hurry.
