Confidence, Confidence Confidence

I would rather be over confident than lacking confidence. Some people say I'm over confident, and I say thank you, Just don't call me unconfident. Why are we conditioned to hang our heads/start to doubt after we continuously fail? We work so hard at perfecting our craft, but when we fail at something multiple time, we start to doubt, We get in our on way. Sports, business endeavors, etc has its ups and downs, Don't doubt your craft. Whatever you choose to do in life is just that, your choice. How do we doubt the goals which we choose to pursue? Failure is only an illusion, the only time we fail is when we stop trying. What comes after failure? Success is right around the corner, STAY CONFIDENT.
