Perfectionism is the enemy of profitability.

I'm not the type to pat myself on the back and all that, but somebody has to be lucky, right? When I got to Dallas, I was struggling - sleeping on the floor with six guys in a three-bedroom apartment. I used to drive around, look at the big houses, and imagine what it would be like to live there and use that as motivation.

I don't think people realize the risks they face every time they create a text, or post on a social network. Unless you expressly make the effort, everything you do online, including texting, has a shelf life of forever.

Don't start a company unless it's an obsession and something you love. If you have an exit strategy, it's not an obsession.

I learned how to become wealthy because I asked the right questions when I was broke.

I'm always afraid of failing. It's great motivation to work harder.

Once you have found out what you love to do, there is only one goal: to be the best in the world at it.
