If you want to become a good player, you need to train well. My experience is that most young players don't know how to practice when they go on the court without a coach. If you are a young tennis player you need to learn how to practice in order to get better. When you practice with a friend, be mentally focused and practice specific strokes like cross court groundstrokes to a target area, serve and returns, specific patterns of play, etc. You also need to run everyball down, and even play balls that bounce outside the lines. If you can get to a ball that is 5 feet wide in practice, you can defenitely get to any wide ball in a match. Next time you go out on the tennis court, put in the same effort and focus as the pros do.
