2. Sheryl Sandberg
Her job as Chief Operating Officer of Facebook is part of the reason Sheryl Sandberg is one of the youngest multi millionaires on the list. With a net worth over $900 million (yah, that’s almost a billion, but who’s counting?) by the time she was 44, you’d think she’d lighten up a bit. Maybe do some serious shopping. Instead, she wrote the book, literally, on how to be a successful woman in a man’s business world. With skills honed at Google prior to the job at Facebook, Sandberg is likely to top the $1 billion mark before her 50th birthday. If you’re approaching 40, get busy: you’ve got a lot of catching up to match Sandberg’s accomplishments.
