A lot of professors give talks titled The Last Lecture. Professors are asked to consider their demise and to ruminate on what matters most to them: What wisdom would we impart to the world if we knew it was our last chance? If we had to vanish tomorrow, what would we want as our legacy?

When Randy Pausch, a computer science professor at Carnegie Mellon, was asked to give such a lecture, he didnt have to imagine it as his last, since he had recently been diagnosed with terminal cancer. But the lecture he gave, Really Achieving Your Childhood Dreams, wasnt about dying. It was about the importance of overcoming obstacles, of enabling the dreams of others, of seizing every moment (because time is all you have and you may find one day that you have less than you think). It was a summation of everything Randy had come to believe. It was about living.
