I play about 2 hours a day and i seperate this period of time in 3 pieces..30 minutes chromatic scales..30 minutes pull of hammer on and about 1 hour minor and major scales..Then if i have time and fun try to play solos from metal bands..Is it enough for someone who wants to play very good guitar someday???(Lets say like the guitarists who played in great metal bands..Randy roads??:))Well?
