Passion and determination are two of the biggest ingredients to becoming successful at whatever one does. There is seldom any excuse for anyone to be content with failure or underachievement.
Like this man in the video shows us, having two short stumps for hands is not enough reason to quit on one's desire to play basketball.
Even though he may never go pro, the fact that he has beaten the odds and worked his skill to the point where it is now, says a lot about how far determination and practice can take you.
