With every effort, I learned a lot. With every mistake and failure, not only mine, but of those around me, I learned what not to do. I also got to study the success of those I did business with as well. I had more than a healthy dose of fear, and an unlimited amount of hope, and more importantly, no limit on time and effort.

One thing we can all control is effort

Open offices keep everyone in tune with what is going on and keep the energy up. If an employee is about privacy, show him or her how to use the lock on the bathroom.

Always look for the fool in the deal. If you don't find one, it's you.

It doesn't matter how many times you fail. It doesn't matter how many times you almost get it right. No-one is going to know or care about your failures, and neither should you. All you have to do is learn from them and those around you. All that matters in business is that you get it right once. Then everyone can tell you how lucky you are.

If you've got $25,000, $50,000, $100,000, you're better off paying off any debt you have because that's a guaranteed return.

If I see a black kid in a hoodie and it's late at night, I'm walking to the other side of the street. And if on that side of the street, there's a guy that has tattoos all over his face, white guy, bald head, tattoos everywhere, I'm walking back to the other side of the street, and the list goes on of stereotypes that we all live up to and are fearful of.
