Failure is great! (See the Failure blog.) It is great because you get to see what is missing in your being or action that brought upon that failure. You get to be strong and to create for the future again, and again, and again. It does not stop. You do not stop working out one day. This is a great idea for another blog.
Getting your emotions out is great. Having someone who understands by getting you is great. But staying in the complaining or being a victim of failure is a waste of time. If you miss a workout day due to sickness or plain laziness, do not find yourself sitting in a cafe for hours telling a friend. If you are doing this, you are just taking time away from actually exercising! The past failure becomes an excuse for something to talk about to divert you from doing what the Nike people say. And that does not involve talking about anything.
