Matthew,
Thanks for your post. I can only speak from my own experiences and challenges, as I am 62 years old and have only been a TAC member for a little over two months. I am new to the guitar, and just completed 6 months of chemotherapy. This treatment put my cancer in remission, but it caused neuropathy in my feet and hands, so playing guitar has been challenging at time. The cancer is in remission, but I struggled with keeping up as well. I noted that Tony constantly advocated to seek progress not perfection. This was challenging to me, but has enabled me to move on even though my method and approaches were anything but perfect. I would encourage you to keep doing your best, and most importantly make sure to have fun.
Respectfully,
David Weber
