Why is sales the only thing that matters in business? I asked Mark Cuban what he wishes every first-time founder knew, and he didn’t hesitate: sales cures all. No sales, no company. That’s it. No exceptions.

If you want to learn how to sell, this is where it starts. Mark tells me why most founders avoid selling, how he built his sales skills going door to door, and the powdered milk company he started out of college that went absolutely nowhere. We also get into why entrepreneurship is harder than anyone admits, and a surprisingly honest moment about what fame has cost him with his kids.

In this clip:
Why it’s easier to start a business today than when Mark was starting out
“Sales cures all,” and why nothing else matters if you can’t sell
Why people avoid selling: they don’t like being told no
“Every no gets you closer to a yes,” and how he lived it selling magazines door to door
Why he’s awful at hiring, and stays out of it at his own companies
The truth nobody tells you: most people fail, and it’s hard
His powdered milk company, and the look on people’s faces when they tasted it
Why founders need to know what they suck at, and bring in people who don’t
“It doesn’t matter how many times you fail. You only have to be right one time.”
Begging his kids to spend time with him, and the price they pay for his fame

These are the business tips I wish every founder heard on day one. Sell, hear no, learn, and keep going. You only need to be right once.
