It's not out of the realm of possiblity but it will take a tremendous amount of dedication on your part. Generally it takes 8-10 years of serious training to become a pro player. But the ability must be there. I say don't set your goals so high initially, just focus on slow improvements and have fun with it as you improve start playing tournaments all the way up to 5.5 if they are no longer compeition for you move on to 6.0 and futures tournaments if that becomes less of a challenge move onto challengers and if you do really well there then you can think about joining the tour. But just focus on slow improvements and dedicate yourself to getting better and see where it takes you. We did have a former 7.0 here named Chris Lewis.
Well I'm not planing to go so high, but what would be nice, what was just question, so if you play for universitie, you play only for scholarship, or you still can become someone after universitie? I'm still looking forward soccer career, and i want to play tennis only as for hobby, and for some competition, but i will see how it goes, if I will reach 5.5 some time what would be really high accomplishment for me. and Chris Lewis, is it the one who was 1983 Wimbledon finalist?
