Tim Gallwey, who wrote “The Inner Game of Tennis,” said athletes such as Henin and Clijsters who devote their lives to sports starting as youngsters often have to get away from the game to regain control of their lives.Gallwey, 72, who was captain of Harvard University's tennis team in the 1959-60 season, said such athletes have a psychological advantage when they return from retirement.
“They’ve had time to step back out of the normal disciplines and grinds of any sport,” he said in a phone interview. “They get to come back with renewed energy and self-determination. Instead of something they have to do as a pro, it’s something they want to do. I admire them, because they’re going back with eyes open.”
