People are capable of great things but some things we just can't do. I, for instance, have not been able to turn myself into a Popsicle despite years of effort. I could make myself insane if I wished though. Anyways if there is a lessoned to be learned it is this: Great success often depends on being able to realize the difference between what you can possibly do and what you just cant do. Or in easier terms, the difference between Popsicles and insanity.
