Bob Cousy (he could play a little basketball) once said:
"Give me a starving, hungry, tough kid with equal talent against a well-fed, average kid any day and the starving, hungry, tough kid will win." I was a kid who was not starved, led a pretty comfortable life, but who learned early on that if I could learn to be tough and MAKE myself stay HUNGRY even when I am old, then things work out better.
I agree 100% with Bob Cousy's statement.
