This video may be old now but to anyone who hasn't watched it this is a valuable "last lecture" from Randy Pausch, a brilliant professor who was diagnosed with liver cancer (which irreparably spread) and had a predicted life-expectancy of 3 months (2 months when he was doing that lecture).
It's a long lecture, I know, (1:18 minutes) but it's definitely worth it:

don't know if you're sarcastic or not, but I still hope you learned something from the video.
