The key is to try and not have to be taught the same lesson twice. It's also to try and reduce the time between the actual failure and learning from it.
In this way, you increase both the frequency and level of winning.
Failure in general is for people who fail. For people who win, failure is just but a part of the process. It's there to show us where we went wrong. If you learn from the mistakes, you'll win. And you will eventually fail again in some way. But, if you learn, you'll win again.
