24. Some of his great quotes:
 “We Make Products That we Want to Use”
"Remembering that I'll be dead soon is the most important
tool I've ever encountered to help me make the big choices in
life. Because almost everything -- all external expectations, all
pride, all fear of embarrassment or failure - these things just fall
away in the face of death, leaving only what is truly important.
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. ...
Stay hungry. Stay foolish."
