Quotation from: Lance Armstrong

When you win, you don't examine it very much, except to congratulate yourself. You can easily, and wrongly, assume it has something to do with your rare qualities as a person. But winning only measures how hard you've worked and howÂ…talented you are; it doesn't particularly define you beyond those characteristics. Losing, on the other hand, really does say something about who you are. Among the things it measures are: do you blame others, or do you own the loss? Do you analyze your failure, or just complain about bad luck?
