Mark Cuban’s first million came from living like he had nothing.
Before he became a billionaire investor and household name, he was a broke 20-something sleeping on a couch in a cramped Dallas apartment with five roommates, driving a beat-up Fiat that leaked oil everywhere it went. He had no closet, no privacy, and certainly no glamorous lifestyle. But that scrappy existence, he now says, was the smartest investment he ever made.

According to Business Insider, the entrepreneur shared his secret to success on BlueSky recently when a fan asked about his best financial decision of all time. His answer surprised many who expected him to name a savvy stock pick or a hot startup investment. Instead, Cuban pointed to something far simpler and more deliberate.
Living Like a College Kid
“Living like a student long after college so that I could start my business,” he wrote.
That humble lifestyle choice, he explained, gave him the cash cushion and mental freedom to take risks that eventually transformed him into one of the wealthiest people in America.
Throughout the 2000s and 2010s, Cuban wrote extensively on his personal blog, Maverick, about how keeping expenses low was one of the most powerful tools young entrepreneurs could use to prepare for success.
In a 2011 entry, he described his early years in vivid detail: the cramped living situation, the unreliable car, and the relentless hustle. Every odd job he took, no matter how unglamorous, was what he called “getting paid to learn.” He bounced between gigs that he was sometimes embarrassed to list on his résumé, but he was convinced each one added skills that would prove valuable later.
His frugality reached extreme levels. Cuban set $20 weekend budgets, survived on happy-hour food, and sipped $12 bottles of cheap sparkling wine while staying up late to study software manuals.
When he finally saved $1,000, the Shark made one indulgence: a new set of towels.
That discipline allowed him to launch MicroSolutions, an IT solutions company he eventually sold to CompuServe for $6 million in 1990. Less than a decade later, he cofounded Broadcast.com, an early streaming platform that Yahoo acquired for a staggering $5.7 billion in 1999.
But Cuban’s success story isn’t just about personal wealth accumulation.
When he sold Broadcast.com, he made sure his employees came along for the ride. Out of 330 employees, 300 became millionaires overnight thanks to his profit-sharing philosophy. At MicroSolutions, he distributed 20 percent of the sale proceeds to his 80 employees, roughly $15,000 each. Even when he sold his majority stake in the Dallas Mavericks, he shared more than $35 million with team employees.
“I just believe it’s the right thing to do. Everyone that contributes should benefit as well,” Cuban explained in response to a question on social media about what happens to workers when businesses get sold.
He added that in every company he’s exited, he’s paid bonuses to employees who stayed at least a year, a practice that stands in sharp contrast to the typical founder-focused windfalls in corporate America.
While a great boss, the former NBA owner dispenses advice to aspiring entrepreneurs with even more zeal. In a 2009 blog post aimed at students, he urged them to live cheaply like he did while building foundational skills in accounting, finance, and statistics so they’d be ready when opportunity knocked.
Today, with an estimated net worth hovering around $6 billion, Cuban remains a vocal advocate for living below your means in your 20s.
