Breaking through barriers is something common to all sports. Some are harder than others, but reaching a level of true mastery is never easy and often requires many years of struggle. Many never achieve it, lacking the necessary will, effort, or simply the ability. All three are required.
As a follow-up to the Chess vs. Tennis post, I'm very pleased to congratulate Andy Murray on his first Grand Slam title, having won the U.S. Open in a five-hour marathon match. No one could doubt his tennis ability before; now, no one can say that he is not a master of the game. It's been interesting to see how he has taken his training and mental preparation to the next level, which is what was needed for his own breakthrough. It can serve as an inspiration for all those looking to achieve mastery of their chosen sport.
