As a young child you were taught the alphabet, phonetics and simple language skills. As you got older your mastery of the English language also improved. Your sentence construction became more and more detailed and interesting. Your vocabulary became larger and your use of descriptive words (adjectives and adverbs) increased. Thus, your sentence structure improved, your paragraphs became more solid and your writing in general got better. Your reports became informative and interesting.
Apply this to your tennis. In tennis, you start with the fundamentals (footwork, ground strokes, serve, volley, etc.). Once you acquire the basics, you can start mixing shots together. Then you can start composing points. Once you can construct points then you can construct games, sets, matches and then tournaments.
You certainly would not enjoy reading a dull book. Think of your tennis as an exciting book. Mix up your shots. Add direction, height, spin and shot selection. Make it fun for someone to watch you play. As in English where you improve your vocabulary, in tennis improve your shot selection. Do not get into the trap of hitting the same shots over and over. Make your game exciting like reading a great book.
Good luck on the courts!
