Never Stop Excelling

OK-I was watching the Olympics last night and was amazed and elaited by Michael Phelps' performance! What makes a person so driven that he breaks so many records and acheives sooooo much by the age 23?? Now how can I motivate my students and children to do that?? Is there some sort of motivating pill I can give them so I can go cheer for them in 4 years!!
