don`t even dare to think about selling ur guitar... u will be sorry after a while... trust me... try to find a good teacher or ask ur friends for help... be patient, every guitarist has experienced some "no-progress" problems, with time and a lot of exercise u will move to next level... just don`give up!!! i`m playing guitar now for about 9 years, and yes, I still suck... :) my friends are telling me that I play pretty well, a 30 year old drummer said I have talent... still i think i suck... :)I am not good at giving advices, but u can`t stop it... especially not now, after 6 years... :)
