It doesn’t matter if you like practice or not, training sessions are crucial to improve your skills, make sure that you don’t have weaknesses that opponents can use and ultimately enable you to win more matches. Technique is the most popular area that players love to spend time on while practicing, but you can also get better with strategy, mental skills, physical shape, and nutritional habits.
Moreover, remember that you should never be happy with your current level because this approach leads to stagnation. Always strive for more, like for example Serena Williams and Maria Sharapova do, and you will see that there are many opportunities to play even better.
