Invention is a flower, innovation is a weed.

In network theory, the value of a system grows as approximately the square of the number of users of the system.

Innovation makes the world go round. It brings prosperity and freedom.

My advice is never let a publicist call you a 'visionary.' I've hung out with the visionaries at the famed Xerox Palo Alto Research Center. I've been a successful Silicon Valley entrepreneur. I wouldn't touch 'visionary' with a 10-foot pole.

Where visionaries can be good at persuasion, CEOs are good at wielding authority. Visionaries transcend organizations, resources, and current realities, while CEOs master them.

I've screwed up and I've overcommitted and it's typical of me.

Grove giveth and Gates taketh away.
