Want to Improve? Compete with a Junior!
Here's a little tip for those who want to improve. Every club has some up-and-coming junior who practices regularly and keeps getting better. Well, why not grab his coattails (even if you are currently better), and try to stay with him? It gives incentive and can lead to great improvement. Make a friendly rivalry out of it, perhaps practice with and play the kid regularly. As he improves, he'll push you to improve.
It may be counter-intuitive, but even if you are better, and practicing with the kid seems to help him more than you (and thereby make it "harder" to stay with him), it works both ways. His improvement will push you to higher levels, either to stay ahead or to stay with him. He probably plays faster than you; his speed will push you to rally and react at a faster pace. As he gets better, he'll push you to find new ways to win points, and suddenly you'll be thinking more about the aspects where you should have an advantage due to experience: serve, receive, heavy spins (topspin and backspin), placement, or just plain consistency. You'll have incentive to develop these aspects in ways you might not do against other players who are not improving so much. The more he adjusts to you and improves, the more you'll adjust to him and improve. And you can ride his improvement as long as you can, right up to a pretty high level. And if he does finally pull away, with you metaphorically kicking and screaming all the way as you try to stay with him, you'll both have improved dramatically, and will be able to point at this star in the future and say, "I was his practice partner." He may even remember you someday during his USATT Hall of Fame induction speech!
