Meet Warren Buffett's Righthand Woman, Age 28

Prepare to feel inadequate. Tracy Britt is 28 years old. She grew up on a farm in Kansas. And she's one of Warren Buffett's top lieutenants. Four years after she was hired fresh out of Harvard Business School to be Buffett's financial assistant, she is now the chairman of four companies within his Berkshire Hathaway empire, accompanies him to meetings, has an office right next door to his—and even sometimes drives him around, the Wall Street Journal reports.

Sources say Britt is already one of the most influential women within Berkshire and has become the "conduit" between Buffett and his various CEOs. Some say she will become a top executive within the next 10 years—and a potential replacement for Buffett's former protégé David Sokol (only without all the shady trading, one assumes). "She's got this wealth of information about what's going on at the Berkshire portfolio companies," says one Berkshire CEO. "She knows exactly what's going on and where Warren's head is at."
