Want to achieve your professional goals? Log out of your Facebook, says success expert Richard St. John.
The bestselling author, who has interviewed over 1,000 successful people including Bill Gates, Richard Branson and Martha Stewart, says that millennials spend too much time on social media. That time, he tells CNBC Make It, could be better spent advancing their career.
"Every minute you spend on social media is a minute lost on your career," says St. John. "One will make you money, the other won't."
He says that young people aren't working that hard on their careers. "It's become ridiculous the ratio of social media time to career time," says St. John.
He points to Facebook founder Mark Zuckerberg as an example. He describes how the tech mogul had very few people he was close with growing up. "He kept to himself and worked in a basement," says St. John. "Now he has a lot of friends."
