A loser is someone who never learn how to win.

The effort applied is more important than the outcome in many circumstances. If you fail to perform at your best due to poor preparation, overconfidence, or any other reason. You become a loser on that day. If you perform your best but are defeated by someone else who just happens to perform better you were merely defeated. winning is not the most important thing, but not being a loser is.

If you have a must win attitude all the time, you will always be as successful as you allow your self to be. they will never know how to lose, much less win because it was never important. If you never learn how to do what it takes to win and achieve what you want, success is not a very likely option.

The wise does at once what the fool does at last.
Baltasar Gracian
