Hello there I am 16 years old and like you I play RS. However, I hardly spend more than an hour playing, but i accomplish everything I wanted to. My goal is to get high combat level, and in one hour, I can do about 4 trips of green dragon hunting. If u like RS a lot, u can make a time table. Instead of following ur friends around, tell them to join in ur clan chat so you can all talk and not have to waste each others' time. Also, if I am playing and it gets to more than an hour, I just log out. I use a clan chat to talk with my buddies and I have managed to make about 1.3m from dragons so far (hey its only my first month as member lol). Finally if you really want to quit, pick up an activity. I do track and play guitar, and in addition to homework and studying I find time to hang out with my friends and play a bit of Runescape. I really suggest u make a RS time table. Good luck, Cheaindian
