Andre Agassi is one of the greatest tennis players of all time and one of the few tennis players to hold all four majors in one year. He had great motivation to succeed and his motivation was the fear of loss. In this excerpt from an article, he clearly describes his motivation: It is 320 yards up the hill Andre Agassi calls “Magic Mountain” on the outskirts of Las Vegas. The desert is on one side; a gated community on the other. It’s Christmas Eve 1999, 38 degrees. Following two hours in the weight room, Agassi sprints up Magic Mountain 14 times. As cars pass by, on the way to holiday dinners, Agassi is sweating, his lungs burning. There’s a look of pain in his eyes. Even Gil Reyes, Agassi’s personal trainer since 1990 and the only other person present, wonders what’s driving this man. ‘I actually stopped him to ask: ‘What’s making you go?’ Reyes said. ‘He said, ‘Gil, it’s just something inside. This is my time. If I don’t do it now, I’ll regret it so much. That’s what it’s all about, eh, Gil? No regrets?’
