Barney reminds me of one of those relentlessly friendly exponents of positive thinking. I am a very positive person, but don't like the whole motivational speaking movement or the self-help book trend. Too gushy and over friendly for me. I think all of those children's characters are annoying.
I cite Roger Bannister as an example of someone with AS who has succeeded. He is intelligent, determined and overcame great odds to succeed both in athletics and medicine. He did what was considered impossible. He charted his own course in life, which engendered the scorn of the sportswriters on Fleet Street, many of whom were not at all athletic and smoked and drank heavily. One internet site said that Roger Bannister overcame childhood paralysis. That was never substantiated in any biography I've read about him, but if it's true, it only adds to his reputation as a man able to overcome great odds. This is true motivation for me. Roger Bannister's life story is a far greater motivator for me than any motivational speaker.
