For me, one of the most influential things he did was his commencement speech to Stanford University in 2005. It’s been viewed on YouTube over 6.5 million times, but if you haven’t seen it before I’ve embedded it below or you can click on the link HERE.
As he states in the commencement address:
"No one wants to die," he said. "Even people who want to go to heaven don't want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life's change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true."
