Mark Cuban’s business experience dates back to his childhood years, when he sold baseball cards and garbage bags as a 9-year-old.

He told Ellen Degeneres on her April 27 show his motivation to sell came from his father, a car upholsterer who taught him to work for things he wanted.

“I’ve been a hustler as long as I can remember,” Cuban says.

He advised people who are getting started in investing to set aside raising money and instead focus on capitalizing on a skill they already have. For the Preston Hollow neighbor, it was selling garbage bags door-to-door.

Cuban also talked about the company that first made him rich — a streaming company called AudioNet he started with his friend from college.

“We grew that, took it public, sold it for a lot of money, and then the rest is history,” he says.

Degeneres asked about a variety of topics in the interview, including Shark Tank, investing and cryptocurrency.

“The way to really be successful in my mind is just being able to get excited about something that you wake up every day looking forward to, and then if you can get really good at it and you want to make money on it, you can,” Cuban says. “And that’s what I try to teach my kids — find something you love to do.”

Cuban also gave some of his money tips:

  • Pay off credit card debt.
  • Always save six months of expenses; you never know what’s going to happen.
  • Invest in what you know. If you’re interested in something, look into it and see if you can invest in it.
