If you haven't yet read Steve Jobs' commencement speech to Stanford in June, you're missing out on something that will inspire you. Find the whole text here, grab a coffee, and keep the Kleenex (r) handy just in case.
Having now read this, I'm going to press through the administrivia clogging my desk and try to mobilize something a little more meaningful this afternoon.
Thanks Steve. That speech is just one more amazing gift you have given the world while you were creating your own life story.
