I dont know if this will help you or not because I've only been playing for about a year. I usually start my practice routine with a few scales, then I move on to some Riffs, Licks, and all the good stuff, hah! Then for about two hours strieght I (Sorry about the spelling) play nothing but songs I like I.E. (my fav band)Rammstein, Papa Roach, P.O.D. and of course, METALLICA!
