I think no matter what you do you go through stages when you play. There was a number of times when I didn't do very well or was tired. It was too much to combine school and tennis altogether. Parents need to step in and say, take a little time off, do something fun.
I played from the time I was seven years old. My father was my first baseman coach. I had opportunities that I never really pursued - with some Miami teams and a few larger colleges, and then I ended up bailing and began cooking.
