SANDY SPRINGS, Ga. -- At Cinnabon's headquarters, there's a constant stream of samples from research and development. While many taste buds are considered, one young lady in particular must sample the sweets.

That's 35-year-old Kat Cole, Cinnabon's president. When she assumed the role, Kat says she wasn't nervous.

"It was exciting," Cole said. "I had given so much of my time learning the industry and being a student of the industry."

The eldest daughter of three girls raised by a single mom, Kat started working as soon as she could.

"If you wanted something, you went and got a job," she explained.

Her first job was in retail in the mall, then she was recruited to join the Hooters team., first as a hostess, then a waitress when she was old enough. Kat says she was always open to opportunities.

(WXIA) -- Forbes has unveiled its 2013 list of America's richest people.

Bill Gates topped the list for the 20th year in a row, with a net worth of $72 billion. He also reclaimed the title of richest person in the world from Mexican investor Carlos Slim. Warren Buffett placed second with $58.5 billion.

America's richest range in age from 29 (Facebook co-founder Dustin Moskovitz, worth $5.2 billion) to 98 (philanthropist David Rockefeller, Sr., worth $2.8 billion). The stakes were so high this year that 61 U.S. billionaires didn't make the cut, according to Forbes.

Seven Georgians are on this year's list. Anne Cox Chambers, 93, is No. 29 with a net worth of $13.5 billion; she is the daughter of Cox Enterprises founder James M. Cox. Her nephew Jim Kennedy, 65, is chairman of the company and is No. 61 on the list with a net worth of $6.7 billion.
