Do you know Randy Pausch?

You should. His story of inspiration in spite of cancer is one of the most inspiring examples of the awesome power of social media. But mostly, it's a profoundly influential lesson about life.

It began as the final lecture of a popular professor dying of pancreatic cancer. It's now a tribute to capturing all that life has to offer, and it's touched millions around the world. (Excuse us while we reach for a Kleenex.) His story has appeared in the Wall Street Journal, on Good Morning America, and an hour-long ABC special featuring Diane Sawyer.

Not to sound trite, but for yourself and all those important to you, be sure to embrace what will forever be known as "The Last Lecture."
