Knowledge is what’s going to save you, not excessive avoidance.

If you do not learn anything new from your past failures, you are bound to repeat them again in the future. I’m against failure in general, but if you do not learn anything from your past failures, you will fail more. And so the best way to avoid excessive failing, is to learn from your past failures.

The problem here is that if you hated failing but you did nothing about it, avoiding trying to do anything unusual, hard, or complex, will not make you fail less. It will actually not reduce your chances of failing again in the future. The only thing that is going to make a difference is understanding why you failed in the past, so that you don’t repeat that again in the future.
