This video inspires me.  For 7 minutes 43 seconds, I am transfixed:

• How is this possible?
• How did he come to be able to do this?
• Where does this level of focus and determination come from? 
• How many times did he fail yet get back up and keep going (despite the fact that failure must have been so painful)? 
• What process does he go through to prepare? 
• How does he look at the obstacles in front of him and see possibilities not obstacles?
