It makes sense intuitively that this type of ‘failure’ or defeat can be a catalyst for great success. You understand that there are times where no matter how hard you try or how hard you work, sometimes you’re not good enough. If success without failure breeds pride, then failure can foster humility, drive and true self-confidence. The flip side is that failure can be so debilitating that people don’t want to experience it again. And some people never are the same once they experience it.
