Tiger Woods the educator. Tiger Woods is the kind of athlete who comes along not once in a generation, but perhaps once in the history of a sport. For the last decade, he has dominated professional golf so completely that he has changed the game and come to exemplify the pursuit of excellence. Tiger has been ranked number one in the world longer than any other competitor. He’s the youngest to win 10 major championships. On his good days, Tiger shows us that the boundaries of sport can be pushed to the edge of perfection; that swinging a golf club and making a ball go into a hole can be one of the most dazzling performances ever.

60 Minutes correspondent Ed Bradley recently spent some time with this purposeful, complicated athlete who fiercely guards his private life. He found a man who, at age 30, is as committed to giving back off the golf course as he is dedicated to his sport. But he also met the man who has come to personify the pure spirit of a champion.

As devoted as Tiger is to the game of golf, he says he gets more satisfaction from another part of his life. At the age of 30, he says he’s ready to make as big an impact off the course, just as his father Earl has predicted for years that he would. This February, he opened the first Tiger Woods Learning Center in Anaheim, Calif., close to where he grew up. The center gives 4th to 12th graders from diverse backgrounds learning experiences they can’t get in their own schools.

"This is so near and dear to my heart. This is more important than any golf shot that I can possibly hit," says Tiger. "But wait a minute. You make a living playing golf. I mean, golf gives you the wherewithal to do all of this," Bradley said. "Golf’s a platform," Tiger replied. "Golf is what I do. It’s definitely not who I am. I hit high draws. I hit high fades. I make putts occasionally. But I don’t get the satisfaction that I get from building this and helping kids and putting a smile on their face and giving them hope."

Tiger can pay for all these centers because he earns so much money playing golf. He’s made more than $70 million on the golf course alone, and his outside income is estimated at $85 million a year. He’s the most recognized athlete in the world. His name and image are a global brand linked to blue-chip companies like American Express. And he’s a promoter’s dream. Television ratings soar when he plays, and that means fatter TV contracts and bigger prize money for the players. Bottom line: Tiger is reported to be on the verge of becoming golf's first billion dollar athlete. But golf is a means to an end.

Tiger Woods is one of the most competitive athletes in the world. But golf does not define who he is. As Woods pointed out that “golf is what he does; not who he is.” Woods is passionate about helping kids get educational opportunities that otherwise wouldn’t be available to them.

Does your job define who you are? Should it? When you understand clearly those things that you are passionate about, you will not be defined by random activities.
