You might want to take a look at this video of Steve Jobs giving his 2005 commencement address at Stanford University. Here is the much quoted quote from that speech:
For the past 33 years, I have looked in the mirror every morning and asked myself, “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “no” for too many days in a row, I know I need to change something. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.
But what exactly does that mean, in practice? It’s a fair question.
For your interest, or not, in a CNN article there’s information about Jobs and his interest and practice of Zen Buddhism.
That’s it, let’s let the chap RIP now.
