Hey guys, I coach tennis at this tennis club and there is this girl who I believe I can take her to the next level. I'm her friend and I'd always play matches with her and I have coached players and I believe that I have had success and that I know exactly what she needs to do to become much better. However, I have coached only 1 tournament player and took him to the semifinals of one open tournament. When I was hitting with her one time, some bystander said, "Are you her coach?" To this she replied jokingly, "He wishes he can coach a top 75 player" and I said "I bet I can coach you to become really good". Then she said, "Hmmm, I'll think about it." What can I do so that she can accept me as a coach? I know I can improve her game and that if I do, the results of her would boost my reputation as a coach.
