Brainwashing is most effective when the one is willing to buy what they are being sold.
Those that "do" are less susceptible to it than those who merely dream, and that is the difference entering the field and accepting the challenge makes.
Some people, even those in sports, never really learn that.
Edit:
"Man versus Nature", "Man versus Man", "Man versus Himself", in every instance it is a competition, and what some people with sell you is the idea you can be a bench sitter and get anywhere you were intended to go.
