Michael Jordan, one of the greatest athletes of all time, achieved the astounding level of success because he was confident in himself. Michael holds the basketballs leagues record for most missed shots. This shows that he didn’t let constant failure stop him from being persistent and pushing through to success and victory.Thomas Edison, was another huge success because he was self-confident enough to endure ten thousand failures. That’s right, it took Edison that many tries before he successfully invented the light bulb. He just thought of the other 9,999 attempts as new discoveries as to how the light bulb doesn’t work. Without self-confidence, we might still not have electric lighting!
