I can remember so clearly listening to Lance Armstrong as he said: "On a given day only one person can win a race and no one wins all the time, we all experience what it feels like to lose, it's how we react that matters"
Michael Jordan has a similar take on it this quote. I managed to snap in a Nike town store: "I can accept failure. Everyone fails at something. But I can't accept not trying."
As we go through life, be it in our sporting life, work life, home life or any aspect of life we are going to encounter failure, we are going to come second, we are going to fall short. That's the way life is. The way that we react is what we can control. Getting back up and giving your best shot the next time is what counts and that's a decision that you have to make.
