If you want to see his lecture that day, it is on TED.com one of my favorite websites. He lived the time he had fully. He did what he could do, did not obsess about the things he could not control, and stayed focused on what was important through his journey. After his terminal diagnosis, he lived very much in the moment, and that lesson alone is something we can all learn from. The book and the lecture are different, and I think they are both worth a look see. Diane Sawyer told me she was doing a special in the next week on his life, and you should all look for it in your area.
Not to change the important subject here, but for those of you that have an appetite for learning. ted.com is the best. As an example, search for a piece call crow vending machine.
