You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.
In order to have great happiness you have to have great pain and unhappiness - otherwise how would you know when you're happy?
