‘Shark Tank’s’ Mark Cuban Says This is His Biggest Fear

Mark Cuban of Shark Tank is a sought-after investor on the ABC reality show. The billionaire (that’s not a typo – it’s a ‘b’) tech guru has several credits to his name besides captain of industry – he’s also a film producer and owner of the Dallas Mavericks.

With his level of success, it’s hard to fathom that the business icon has any fears. Apparently, Cuban does have a few things he’s afraid of, with this being what scares him the most.

Walks the walk on hard work

According to Business Insider, Cuban met his future wife, Tiffany Stewart, at a Dallas gym in 1997. The couple tied the knot in 2002, and now have three children – daughters Alexa, 15, and Alyssa, 12, and son Jake, 8. Though he’s a dedicated family man, Cuban still has a hard time ending his work day.

His excessive work ethic was a sticky issue early on in his relationship with Stewart, where she told The New York Times that “scheduling problems” were a point of contention between them for awhile. Stewart came to realize that Cuban’s strong drive was a main part of his identity. “I always know I’m not going to be No. 1,” Stewart said in the article, referencing Cuban’s late nights on the computer. “He can’t turn it off. He just can’t!”

Raising a family when you’re a billionaire

Cuban’s wealth and success are a result of his hard work, something he and Stewart are trying to teach their children. The couple avoids spoiling their kids, wanting to instill in them a solid set of values.

“I’m not the dad that comes home with a ton of presents. I am the dad that says, ‘Pick that up. Take that; put it in the sink. No, you have to earn that,’” Cuban said, according to Business Insider. “I want them to recognize that the only thing special about themselves is what they make for themselves. They have to be themselves. They can’t be Mark Cuban’s or Tiffany Cuban’s son or daughter. They have to be adults and they have to carry their own weight.”

His greatest fear

The Shark Tank star has mastered many career achievements, yet he still gets scared at the thought of certain things. He revealed his greatest fear has to do with his children. “That’s my biggest fear that they grow up to be entitled jerks,” he told Dallas’ WFAA in 2015. “It is the scariest thing in my life, ever. After their health, there’s nothing scarier. My wife and I talk about it all the time.”

The billionaire exec said that the idea of spoiling his kids is “terrifying,” especially since he was brought up as “middle class as it comes” and learned the value of hard work. Cuban tries to focus on teaching his kids to appreciate education and approach life with curiosity. “I push them to value learning, to be excited about learning, I push them to be inquisitive about the world and understand what’s going on,” he said.

Cuban also wants his kids to know they will make mistakes, and they can learn from them. “I’m going to try to be that dad that says, ‘You have to think for yourself. I can’t be there all the time,'” he said. “And I want to be here while you’re learning how to make decisions so we can talk about it. If they’re not capable of making mistakes, then they’ll make bigger mistakes. That’s the way I’ve thought about it.”

ABC’s Shark Tank airs on Sunday nights.
