Kevin O'Leary

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.

If I were the president of the United States, I would make unions illegal. They no longer serve a functional purpose in democracy, in my view.

Working 24 hours a day isn't enough anymore. You have to be willing to sacrifice everything to be successful, including your personal life, your family life, maybe more. If people think it's any less, they're wrong, and they will fail.

I'm proud to be on the CBC and to see the management here represents both sides of every story. This is what's unique about the new CBC: you get a Kevin O'Leary on it when five years ago you wouldn't.

I think a book is your calling card, your business card.

The only reason to do business is to make money; that's the only reason for doing business.

Know everything about the companies and people you are going to be negotiating with. Insist on getting the names of everyone participating in the negotiations. Leave no stone unturned; find out as much as you can.

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

For whatever reason somebody can be convinced to buy a PC, it opens up a whole new market for all of us in the software business.

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.

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.

There's only one side with me. You get the right side. You get the correct version of the facts.
