Nick's story is very interesting. He doesn't have arms and hands and only 1 foot that is of any use to him.
However, it's simply amazing what he can do and where he gets his strength from. Instead of sitting around all day feeling sorry for himself, he travels the world speaking to groups of a 100,000 at a time, not about his disabilities, but about his abilities.
What's your downfall? Are you letting it affect your life, or are you using it to your advantage?
