This is Steve Jobs, speaking at Stanford's graduation in two thousand five.

I left school after six months and sat in on the classes I actually loved.

"You can't connect the dots looking forward; you can only connect them looking backward."

Ten years on it was a huge company, and then the board pushed me out of it.

When the answer kept coming back no, day after day, I knew I had to change something.

He closed that speech with four words. "Stay Hungry. Stay Foolish."
