Tennis advice needed
I am currently 17 years old, and I am getting good at tennis just now, I started late tennis, but when I went to play my first ITF tournaments and saw youngsters play better I had this question in my mind is, I can barely win 1 round in ITF, how can I win any in ATP as I am getting soon 18 years old and by then I can't play ITF anymore, I wanted to know is it worth spending all this money?
and will I have a chance to improve in ATP if I haven't gone well in ITF??
I am mentally week about this situation, though if it is possible to get better in seniors I may double my efforts.
