At points in their lives, every hero was at a time a failure. They were probably "failures" for years. Maybe decades. They woke up morning after morning being true failures. I know where I came from. I know where I am. I know where I can go. I know where I can go back to. Their defining attribute was that they saw failure as motivation instead of an excuse to give up. They acted as heroes and fought inertia. They fought doubt. They fought the fear of the present.
Are you a failure?
