Learn and move on

Guts are a combination of confidence, courage, conviction, strength of character, stick-to-itiveness, pugnaciousness, backbone, and intestinal fortitude. They are mandatory for anyone who wants to get to and stay at the top. - D. A. Benton

There is great pleasure in achieving and succeeding when others say you cannot. The goal is not to never fail, but to be able to pick yourself up after a failure, learn from it...and move on.  With enough patience and perseverance...soon your difficulties and obstacles will disappear.
