I've been playing for 6-7 years and quit lessons one year ago because of the cost and have been steadily improving on my own. A few months after quiting lessons I started daily practice with a metronome(1 hour) and at least another 3 hours daily of just playing but the problem is I don't seem to be able to preform at the same level everyday accuracy,speed etc. some days I'm dead on and others its like I haven't played in months. Any advice maybe something I'm not seeing any help would be greatly Appreciated
