I use video, and this is what I struggle with. I see so many things I think need fixing. I work on one piece for 10 minutes, than I work on something else for 10 min. Nothing ever changes when you practice like that. What I need is a priority piece and think of nothing else while practicing besides that piece. I just don't know what mine is at the moment, and that leads me to be all over the place and not changing anything. I need to get back on evolvr.
