Have you experienced TED talks? Here's one to get you started, but really there's something there to interest everyone and anyone. One of my favorites of all time is Richard St. John's humorous, insightful and short speech "8 secrets of success". What I love about his eight secrets is that, in fact, none of them are a secret. He's pretty funny too!
Of the eight, 'Push' and 'Persist' and his explanations of them are my two favorites. I have all 8 (well, 9 really) printed in big letters and hanging on my wall.
