Is there any truth to the notion that once someone has accomplished something big and gains notoriety (positive or negative) for that accomplishment that they somehow just are in the know, and we should listen to what they have to say?

We each can probably think of excellent examples on both sides of the argument. Consider what follows as "food for thought." In the December 2005 issue of Business 2.0 Magazine, 30 "business visionaries" were asked, "...what single philosophy they swear by more than any other--in business, life, or both." To be fair, the article gave a paragraph or two explanation about each quote, but you'll get the gist. You will need to decide for yourself just how much weight you will give to each pearl of wisdom, and whether or not it is something you can benefit from taking to heart.
