The Simple Yet Devastatingly Effective Secret To Warren Buffett and Oprah Winfrey’s Success

Despite working in different industries, Warren Buffett and Oprah Winfrey share a key to success.

On the surface, Warren Buffett and Oprah Winfrey couldn’t be more different in their backgrounds and careers. Yet both have built empires using similar methods. It’s what Buffett calls his “circle of competence” or, as Winfrey explained it in the miniseries Making Oprah, “running your own race.” 

Whether it's Buffett’s nearly 10% stake in Coca-Cola, which he drinks several cans of a day, or Winfrey’s 10X on Weight Watchers stock, an area she’s often discussed her familiarity with, the two follow a similar investing tenet. They both continually choose areas they know best, which they know how to capitalize on in ways others don’t.
