Focused vs unfocused practice
I often find myself watching sports and use that time to practice guitar (and workout/mobility training). While I think this is time well spent since I enjoy sports and I am still improving my physical health and guitar playing, I am wondering just how much more focused practice will improve my playing.
By that, I mean sitting for a solid half hour undisturbed and completely focused on my practice. I feel like I'm still getting some benefit from practicing while watching games (chord change practice, scales, etc), but just wonder how much more effective focused practice sessions are. I'm looking for input from others who may have tried both and noticed a difference in improvement.
