I have a coach since I started playing tennis 5 months ago. I have met him like 10 times so far. He was really good in getting me onboard this game in developing proper forms. However, the past few lessons I don't think I need him that much. During our lessons, we basically just play games and then he will point out my errors. I know all the errors he points out because from time to time I video myself playing and then watch myself in my computer. I have invest close to $300 in buying coaching DVDs so I know where I went wrong mostly. It just takes time to get me to the correct form through practice. My coach is good but now I'm wondering whether it's worth the cost of the lessons.
