1. Andre Agassi
Did anybody have more of a love-hate relationship with their sport than Agassi? The American experienced extraordinary success in his sport. An eight-time Grand Slam winner, Agassi was also an Olympic gold medallist. But despite this, he claimed to have no love for the sport.

In his 2009 autobiography, he revealed his loathing for his life as a tennis player. “I play tennis for a living even though I hate tennis, hate it with a dark and secret passion and always have,” he wrote. That’s a shocking thing for an elite athlete to openly admit. Many people hate their jobs but they expect athletes to feel as though they are living the dream.
