Hi, I am in the same boat sort of. Didn't play for may years, and got back into it after kids grown etc... I finally decided to take lessons again after 30 years. I started back with lessons in March and am really enjoying it. Definately worth it to have someone who will give you assignments and critique your playing. It seems much more structured and gives me the opprotunity to complete the piece I am working on before going on. I still play a bit of the other pieces too. But, mainly concentrate on the assignments. Overall it would be a good decision for you based on my own experience, Good Luck
