Did you know that Roger Federer has only won 51% of all his points played in his entire career and Nedal has a very similar statistic. We're talking about arguably the 2 top players of all time. Think about that for a second. They lose 1 out of 2 points! What does this tell you? Well, for a start, they win the big points, they win the points that matter. How? Because their mental approach, mental strength and toughness is so good!
