"It doesn't matter how many times you fail. You only have to be right once and then everyone can tell you that you are an overnight success."

"Sweat equity is the most valuable equity there is."

"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."

"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."

"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."

"Sales cure all. Know how your company will make money and how you will actually make sales."

"In the past, people worked for large corporations because it was safe. In the future, working for a large corporation will be the riskiest thing you can do."

"Work like there is someone working 24 hours a day to take it all away from you."

"Everyone's got ideas. The hard part is doing the homework to know if the idea could work in an industry."

"I still work hard to know my business. I'm continuously looking for ways to improve all my companies."

"The sport of business is the ultimate competition. It's 7x24x365xforever."
