Phil Mickelson
Psychology
Phil Mickelson showed immense interest in golfing as a toddler. His career began in earnest when he was at Arizona State, where he won three NCAA individual championships, before turning pro at age 22. Long known for his inability to win a major despite his elite skills, "Lefty" finally got the monkey off his back with a dramatic victory at the 2004 Masters, and went on to claim four more major championships over the following decade.
