As a test of whether or not I still have the ability to learn something, I am going for a ham radio license test in December. Is it still possible to learn something new? Can I pass a test? Yes is the answer to both.
As soon as that is over my plan is to focus on guitar again. As the guy in the video suggests, listening to recordings of yourself playing can help to spot flaws you might not notice while trying to get through a piece of music. A cellphone camera is a tool to make quick recordings. A friend who is also in his 60s has no clue how he sounds, and his practice routine has reinforced his mistakes. There is a need for me to come up with a practice routine that avoids that trap.
I just subscribed to Tomas Michaud's YouTube channel so I can find his videos again by the end of next month. Thank you for posting that one.
