I have great people working for me now. I surround myself with smart people.

When I turned 50, something clicked in my head and I said, 'I'm not going to live to 100. I'm half-cooked already.' I set the family down and I said, 'Listen everybody, we're now entering the decade of Daddy. We're going to start doing things that I want to do.

Imagine how foolish you'd look if, like one clever salesman who once pitched to me, you tried to license your product to a big industry player without knowing they just launched a competing product. With the right background research, he could have avoided that and other landmines - and so can you.

I'm starting to think about things that I want to do, things that are fun. One of them is driving a car like a Porsche. I've driven a lot of cars - sedans, trucks and big family vehicles all year long. But there's nothing like a four-wheel-drive Porsche.

I keep anywhere between 5-10 percent of my net worth in venture ideas.

Being an employee is a bad outcome. You want to avoid that. Being an employee is never a good outcome. That's just an opinion.

Business is war. I go out there, I want to kill the competitors. I want to make their lives miserable. I want to steal their market share. I want them to fear me and I want everyone on my team thinking we're going to win.
