The strength of the human spirit always confounds me. Determination and focus. Its not that we can do all things, but we certainly can do most things we put our minds to. Naturally people will say "well, I really really want to be rich", can I do that? I don't think that will happen to everyone even if you have the best teacher or motivational coaches, but at least you would have gave it your best shot. Isn't that most important ... that you have aimed for the stars, pulled back an arrow the best you can and gave it your best shot ... rather than wishing upon a star and slumping back to your regular humdrum activity.
This guy's a champ. .... Just do it ... you'd be amazed at what you can achieve.
