With the olympics opening tonight, I sometimes think of all the athletes who train their whole lives and get injured right before making it to the big time.

Lost opportunities come and go, even some once-in-a-lifetime ones. But what you can keep no matter what is the experience and the wisdom you gained by trying to reach your dreams.
It doesn't matter how many times you fall in life, you can keep you head up if you know you kept on trying.
