I'd rather invest in an entrepreneur who has failed before than one who assumes success from day one.

You may lose your wife, you may lose your dog, your mother may hate you. None of those things matter. What matters is that you achieve success and become free. Then you can do whatever you like.

All businesses require capital, management and labor, and business executives, wanting to grow and maintain profitable enterprises, have a strong incentive to keep costs, including labor, as low as possible.

Nobody forces you to work at Wal-Mart. Start your own business! Sell something to Wal-Mart!

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.

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 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.

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.

Money is my military, each dollar a soldier. I never send my money into battle unprepared and undefended. I send it to conquer and take currency prisoner and bring it back to me.

Money has no grey areas. You either make it or you lose it.

Here's how I think of my money - as soldiers - I send them out to war everyday. I want them to take prisoners and come home, so there's more of them.

Money equals freedom.

I have met many entrepreneurs who have the passion and even the work ethic to succeed - but who are so obsessed with an idea that they don't see its obvious flaws. Think about that. If you can't even acknowledge your failures, how can you cut the rope and move on?
