My sister introduced me to the Randy Pausch phenomenon on the weekend which I think she herself stumbled upon, and just in time. There is a special on ABC this Wednesday at 10pm about him and I'm blogging about this to encourage you to watch it. I'm certain it will at the very least inspire.
In the meantime, invest the next 11 minutes in something great and watch his Last Lecture.

(4/9/08 - sorry, turns out what I saw was just a reprisal - the actual lecture is 76 minutes long)
