Oracle's Larry Ellison has been a sailor since his 20s.

Ellison's Oracle Team USA won the America's Cup race this year.

"It's funny, I realized after losing the America's Cup twice, my personality didn't allow me to quit while I'm losing," Ellison told Charlie Rose. "After winning the America's Cup, I discovered my personality doesn't allow me to quit while I'm winning. So I'm kind of trapped. I just can't quit."

Ellison became interested in sailing when he read a story in National Geographic about Robin Lee Graham, who was the youngest person to circle the globe by himself aboard his sailboat. At the time, Ellison was a teenager and envied Graham's adventurous spirit. He's been sailing ever since.
