12 Quotes That Take You Inside The Mind Of Billionaire Mavs Owner Mark Cuban

His first job was tending bar in Dallas. Then he took a gig as a computer salesman. He was fired - and he realized he "was never going to be a very good employee."

So he started his first company, MicroSolutions, which he sold for $6 million.

He did even better with his next company - about 1,000 times better. He founded Broadcast.com and sold it to Yahoo for almost $6 billion.

Almost immediately, Cuban sold all of his Yahoo stock netting $2 billion in cash for himself. Weeks later, the market crashed.

Since then, Cuban has continued to work and invest. He owns the Dallas Mavericks and a cable channel, plus he's all over the media - taking bites out of would-be entrepreneurs on ABC's pitch show "Shark Tank" and lighting up the conference circuit.

Cuban is known for saying what other people only think. Here are some of our favorite quotes.
