It was 50 years ago that Warren Buffett took over Berkshire Hathaway. Yet believe it or not, there are some things the world's second richest man doesn't like about his job.
"One thing I don't like is when I have to make a change in management," Buffett told CNBC's On the Money in an interview. "When I have to tell somebody I think somebody else can do a better job."
Berkshire's chief called having to fire someone "pure agony, and I usually postpone it and suck my thumb and do all kinds of things before I finally carry it out."
At the helm of the Omaha-based conglomerate since 1965, he's built it into the fourth-largest publicly-traded company, trailing only Apple, Google and Exxon Mobil in market capitalization. That perch has afforded him a certain degree of autonomy, he explains.
"I don't have to do anything I don't believe in." Buffett says. "All my decisions are elective."
