I was born to sell it as a kid. I think it's partially innate, and partly it's because my parents were always very clear: if I needed anything that wasn't a necessity, I was going to have to save my money and buy it myself. That meant not only did I have to buy basketball shoes, but I had to figure out how to pay for college as well.

Sweat equity is the most valuable equity there is. Know your business and industry better than anyone else in the world. Love what you do or don't do it.

I'm the one guy who says don't force the stupid people to be quiet. I want to know who the morons are.

Leaders don't look backwards to condemn what has already been done; they look forward to create a better future.

I can't say it enough that learning how to learn is one of the greatest skills anyone can have. It's why I advocate that everyone go to college.

I hate politics. It's slimy. Any job where people pander for votes, I don't like. The country has gotten so partisan that if you're not on my side, you're the enemy. The only thing I ever try to support is a third party, like Unity08. We need more parties and more choice.

Talent without effort is wasted talent. And while effort is the one thing you can control in your life, applying that effort intelligently is next on the list.

Mark Cuban

Sweat equity is the best equity.

I love entrepreneurship because that's what makes this country grow, and if I can help companies grow, I am creating jobs; I am setting foundations for future generations. It sends the message that the American Dream is alive and well.

Whatever you are studying right now, if you are not getting up to speed on deep learning, neural networks, etc., you lose. We are going through the process where software will automate software, automation will automate automation.

My guiding principle and motivation was that I wanted to retire by the time I turned 35. There actually are two books that I bought and still have - Paul Terhost's 'Cashing In On the American Dream: How to Retire at 35' and Andrew Tobias's 'The Only Investment Guide You'll Ever Need' - that were my personal financial road map.

I don't care what anyone says. Being rich is a good thing.

Mark Cuban

When you post something, when you text something, you lose ownership of it when you hit enter or send. Who you send it to, where you post it, they take ownership of that information whether you like it or not. Unfortunately, you don't lose responsibility for that text or post.

It is so much easier to be nice, to be respectful, to put yourself in your customers' shoes and try to understand how you might help them before they ask for help, than it is to try to mend a broken customer relationship.

What I've learned is that if you really want to be successful at something, you'll find that you put the time in. You won't just ask somebody if it's a good idea, you'll go figure out if it's a good idea.

Mark Cuban

Being rich is a good thing. Not just in the obvious sense of benefitting you and your family, but in the broader sense. Profits are not a zero sum game. The more you make, the more of a financial impact you can have.

Mark Cuban

What I've learned in these 11 years is you just got to stay focused and believe in yourself and trust your own ability and judgment.

Mark Cuban

Because if you're prepared and you know what it takes, it's not a risk. You just have to figure out how to get there. There is always a way to get there.

Mark Cuban

I look at my annual budgets for everything and anything, and I look to see where I can save the most money on those items. Saving 30% to 50% buying in bulk - replenishable items from toothpaste to soup, or whatever I use a lot of - is the best guaranteed return on investment you can get anywhere.

Mark Cuban

Wherever I see people doing something the way it's always been done, the way it's 'supposed' to be done, following the same old trends, well, that's just a big red flag to me to go look somewhere else.

Mark Cuban

If you can't admit a failure, you're not an entrepreneur. You are not a good business person. There's nothing brilliant about what you are doing.
