In reply to youngclimber:
Ah man, I wish I had been climbing since i was 14! I'll give you the advice that I would give a younger version of myself when i get that damned time machine working; find a coach.
There are loads of youth climbing squads which you should still just about squeeze into at 16 years old, if not, if you can possibly afford it, get some one to one coaching and soak up their advice like a sponge.
You are right not to be worried about overtraining or injuries, worrying is pointless, but you should be aware of the risks and doing everything you can to minimise the chances of ever suffering from problems in the future by doing things correctly right now.
I climbed f7c+ in 2011, then I dislocated my shoulder 5 times and am only now just getting back near that standard. Think about that, that's like you injuring yourself tomorrow not being able to climb hard again until you are 20 years old. Twenty. Seem like a lifetime away?
My shoulder dislocated not because I pulled some gnarly english 7b dynamic lunge, but because I had a weakness caused by not exercising the boring support muscles around the joint, not warming up, not warming down, not listening to my body for too long. One of the dislocations happened on a 6A slab!
My point is, if I had treated my body right when it felt fit and strong, it would have stayed fit and strong.
I know its boring but if you get into a habit of warming up carefully, warming down and stretching and having a program of antagonist and supporting muscle exercises to run along with your climbing, you will outlast most of us broken old punters.
Go and find a coach, and hopefully he or she will tell you something similar, by all means try to improve as quickly as you can, but listen to their advice, listen to your body and enjoy your climbing.
