This is the last lecture given by a Carnegie Mellon professor, Randy Pausch, who has terminal cancer. Technically, it's about achieving your childhood dreams... it's long, but contains a lot of the wisdom he has gained over his life. What's remarkable is what a good attitude he has in spite of the fact he is dying of cancer. Although it's inspirational, there another less inspiring subtext and that is people rarely change. He was a happy kid, he was happy and an overachiever in life, and he remains happy even when faced with cancer.
