In 2007 Computer science professor Randy Pausch, who had terminal pancreatic cancer, delivered his "last lecture." Pausch used the time to express his gratitude rather than focusing on his terrible misfortune. In an hour-long taped presentation that earned worldwide acclaim as it spread throughout the Internet, Pausch summarized his philosophy, and spoke of the importance of ambition, hard work and perseverance. Pausch's main objective was to leave a meaningful legacy for his three children - and he succeeded brilliantly. His book, written with Jeffrey Zaslow, expands on the themes in his lecture, entitled "Really Achieving Your Childhood Dreams."
