“I play to win, whether during practice or a real game. And I will not let anything get in the way of me and my competitive enthusiasm to win.”
“To be successful you have to be selfish, or else you never achieve. And once you get to your highest level, then you have to be unselfish. Stay reachable. Stay in touch. Don't isolate.”

The greatest sportsman summarized this perfectly -- before you winning your way to the top, you have to be fiercely competitive, you have to be selfish, you have to crush every competitors, teamates or opponents, that are in your way. 文无第一,武无第二. This is true not only in sports but in academics competitions, and real world business.
Team play and being unselfish are for the winners at the top only. Before you become the top winner, it is chicken soup for the losers.
