When Walt Disney answered to the question whether he was an optimist, that he was an optimal behaviorist, he explained that he always acted to his optimal capacity. In other words, his optimism was conquered, it was the result of discipline. Disney's unyielding faith might as well be the result of discipline. The Disney secret to be always upbeat in the face of lack of money and of people's lack of faith in his projects, certainly has to do with dignity.
Walt Disney was a lover of beauty; he was a perfectionist. Disney's unyielding faith corresponds to his demand of perfection from himself.
