Grow up! Quit whining, asking for advice, you going to be a star listening to our tips? Go out there and be a man! I started playing at like 12 with my brother who was 21, I lost, lost, lost, but had desire, so got better and wipped him. Just go do your own thing or stop whining. Can't serve? Then PRACTICE! Poor forehand? PRACTICE! There is no magical formula we can give you to lean, do what we did, that is work our tails off to get good, lose, win, win, lose, just fight through it. Run up to 5 miles, but also do sprints. Practice against a wall, just STOP with the "If I only hold my hand ......." nonsense. I'm sorry, I just see so many wooses on this forum, can't play there is no suggestion for you except for you to play and learn yourself, how do you think we learned? Even those who go to Tennis Academies only learn what they are taught, Tennis is much more than what you are taught, it's like boxing, unique to you.
