Failure is so important. We speak about success all the time. It is the ability to resist failure or use failure that often leads to greater success. I've met people who don't want to try for fear of failing.
Why do I talk about the benefits of failure? Simply because failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me.
