For many people, their 30s are the period of their lives where the biggest changes take place, like moving across the country, changing career paths, or settling down.
It’s also the decade when many people move ahead professionally. There are plenty of incredibly successful people who got their big career breaks in their 30s. Megyn Kelly, for example, left a nine-year legal career at age 33 to work in media, while Oprah Winfrey didn’t become a national icon until her show became syndicated when she was 32.
Read on to learn about nine successful people who made their careers in their 30s.
