You’re likely to earn significantly more if you go to college and get your bachelor’s degree, or make it even further, according to government statistics. But for the richest of the rich, the normal rules don’t seem to apply.
Whether through innate ambition and skill or sheer luck, a number of extremely wealthy leaders like Bill Gates, Mark Zuckerberg, and Richard Branson made it to where they are without the traditional educational credentials. In fact, research firm Wealth-X found in 2016 that nearly a third of the world’s billionaires didn’t have a bachelor’s degree.
Here are 15 insanely successful people that you may not realize never went to college, or abandoned higher education once they got there.

DeGeneres is one of the most successful comedians and hosts in Hollywood history, but she had to work her way there over time. She enrolled in the University of New Orleans, but dropped out after only one semester. She worked odd jobs from house painter to vacuum salesperson to oyster shucker (yes, really). In the ’80s, she was doing standup at comedy clubs and finally got a national spotlight on Johnny Carson’s Tonight Show. By the ’90s, she had her own sitcom, and of course, now she’s the queen of daytime TV with her talk show Ellen.

Ellison has had a colorful life, from being born the son of a single mother in the Bronx to buying his own Hawaiian island. He also dropped out of college twice.

After developing computer and programming skills in several jobs, though, he was able to launch his own software company, Oracle, and went on to become a tech legend.

Like many of the other tech mavens of the 1980s and ’90s, Dell showed an early interest in computers. But his parents wanted him to be a doctor, so he enrolled at the University of Texas at Austin as a premed student. He left after only one year because his side work refurbishing and selling computers became so successful. Today he’s still in the same basic business as CEO of Dell Technologies.

No one personifies millennial fame quite like Kim Kardashian and her family, who put their lavish lifestyle in front of cameras for Keeping Up with the Kardashians, and successfully built a mammoth business off their names. Kourtney and Rob Kardashian are the only children in the Kardashian and Jenner clan who graduated from college. Kim attended Pierce College in Los Angeles and worked at the family’s Dash store when the E! reality show got going, and she soon left both behind. Now virtually synonymous with selfies, Kim has said she would like to continue her education when she’s older and perhaps even get a law degree.

In previous eras, it was less common to graduate from college, but it’s still stunning that Rockefeller, one of the wealthiest Americans of all time, didn’t get any higher learning.

No one knew how to sell a burger with a smile like Dave Thomas. The founder and former CEO of Wendy’s didn’t make it to college, having left high school to work at the Hobby House Restaurant in Fort Wayne, Indiana. He opened his first Wendy’s in 1969, and eventually turned it into a fast-food empire thanks in no small part to his role as charming mascot in a number of TV ads.

Ford revolutionized manufacturing and transportation with his car company’s innovation, the assembly line.
