I don't understand the point of this article. "Looking deep within yourself" is one way to find inspiration/motivation. To write off an entire library of books/tapes/speeches/programs as manufactured and ineffective is absurd. Personal change is extremely hard - ask a smoker/obese person who's tried to turn things around - and everyone finds strength in different things. If that means listening to a compelling personal story expertly delivered on stage - who are we to judge?
