I normaly practice from 1 to 2 hours a day. I cant fathem playing for 4,5,7, or 10 hours. Guess my hand, wrist, and fingers fatigue to quickly at the moment to even think of it. Got to say very good post . I learned alot. I normaly switch up alot during practice / noodeling? I'll work on a lesson for a bit then go back to a song I like. Anyways... thanks for the info yall I will defenatly try to impliment these sugestions into my practice... Well except the 10 hour thing. Wife would devorce me...lol
