Slow and steady wins the race
If staying-power was a kind of sport, Roger Federer would be its champion. He did not burst onto the scene like Rafael Nadal, who already won the French Open at 19. Neither was he a slow maturer like Andre Agassi, who had to play tennis professionally for ten years before he got to be number one in the rankings. Federer's virtues couldn't be more Swiss: staying power, humility, and hard work. As American tennis legend Billie Jean King put it: "champions keep playing until they get it right."
