Hi. I am 18 years 10 months old right now and i have been playing tennis for 9 months now. I have played 10-12 hours a week so far(if i could, i would play 15-20 hours). My NTRP ranking is 3.0(i am almost 3.5). I really regret because i didn't start playing it when i was so young. I know i have the disadvantage of being late and so i try hard and have a discipline. I have a so great desire that i would play 10 hours a day if my body let me do it. I really am never bored of playing tennis. I will change my location and play a lot more of tennis everyday after next month. What would you recommend me to do? What do you think? What is the highest level i can reach by playing 2-3 hours a day? Am i too late? Can you encourage me a little bit please?:-| Thank you.
