http://www.youtube.com/watch?v=ji5_MqicxSo&e Give this a watch, but have some Kleenex around for the end. This is from the Carnegie Mellon Professor Randy Pausch, who gave his last lecture at the university Sept. 18, 2007. He did a shorter version of this on Oprah but this full lecture is well worth the watch. He is a former Disney Imagineer who worked on the Aladdin VR ride at Disney quest. But what makes this special is his outlook on life, I won't spoil it any more..... just watch, overcome the walls and carpe diem.
Last fall while watching ABC news this story was feature. Great example of keeping it positive. Wish I had him as a professor.
