I've been an entrepreneur three times. I started three companies.

The difference between a vision and a hallucination is that other people can see the vision.

When I talk to entrepreneurs today, I feel like the grandfather who was in the Civil War.

So I came from an environment where I was starved for information, starved for connection.

On the back end, software programming tools and Internet-based services make it easy to launch new global software-powered start-ups in many industries - without the need to invest in new infrastructure and train new employees.

I always had the old-school model that I'm going to work for as long as I'm relevant and focus on for-profit activities and someday when I retire I'm going to learn about philanthropy.

I don't waste time being depressed.
