Hi @jeffrey M, i guess under TACster definitions I am an “intermediate” player, but I wonder.
Anyway, two things I did at the first of the Year. First, I picked an artist (could be a genre, inter-related, but I chose Woody Guthrie) to learn a minimum of 1 song per month, and either post it or play it live or VOM. A true intermediate could push 5 songs into 3 months, and it would have the same focus and encouragement effect. And you will find music you love that you may not know about, or may have overlooked.
The second thing I have done this year is to encourage myself to work on finger-picking and figure out ways to finger pick the songs I am playing. I added doing something every day into that pledge and it is now part of my Routine. Putting a time string on that kind of effort is also challenging and leads to progress.
Good luck, and looking forward to hearing about success and unstuckedness.
