Randy Pausch, a lecturer at Carnegie Mellon was diagnosed with cancer (and has since passed). His book 'The Last Lecture' and the video of the lecture are both fantastic. However, today I just found another lecture he did prior to passing on time management.

Great reinforcement, plus a few new things. For those who want to have more time later, invest the hour and a quarter now by watching this video

***UPDATE***

Although Randy mentions that no one should need to take notes during this lecture, I did anyway. You can see my notes in the photo below.
