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.'

When you come to ‘Shark Tank,’ the only person you should listen to is me, because you know you’re getting the truth. I’ll decide if it’s worth it, and after I’m finished, the rest of the people can look into it.

Once in a while, I see my fellow TV investors praise a business just because they like the entrepreneur behind it. That kind of thinking might make you feel warm and fuzzy inside – but let’s get back to reality.

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.

When you’re travelling, your day is jam-packed. I just don’t have time to whip out a PC all the time. But I can whip out a BlackBerry and tweet. I keep a constant diary of where I’m at and why I’m there.

There are a lot of impractical things about owning a Porsche. But they’re all offset by the driving experience. It really is unique. Lamborghinis and Ferraris come close. And they are more powerful, but they don’t handle like a Porsche.

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.
