To relate to domains that may not seem connected at first. A certain creativity that allows people to be effective."

"It's fine to celebrate success but it is more important to heed the lessons of failure."

"Microsoft was founded with a vision of a computer on every desk, and in every home. We've never wavered from that vision. I never imagined what an incredible and important company would spring from those original ideas."

"Your most unhappy customers are your greatest source of learning."
