Hi Eva,
What you describe mirrors my comment in the 2024 Top 1 Guitar related Frustrating Aspect topic. I hit a plateau, and feel like I can’t advance. I’ve come to accept that this is part of the journey.
My own story: I had completed Grade 2 in late 2023, was trying to consolidate, and felt stuck - much as you describe. I’ve engaged one of Justin’s teachers to help me through this. It’s been fabulous - the focus is on learning songs, and those songs use techniques that I’ve been stuck on. At the same time, I’m slowly working my way through the Grade 3 lessons, continue to think about theory, and am doing ear training. Now when I hit the inevitable plateau I mentioned above - whether in the songs from the teacher or from Justin’s lessons - I set the thing aside for a while. I’ll return to it, and it’s fresh again. I don’t expect to be an “intermediate” player for at least another year, and perhaps it will be longer. It’s all good - I can play things I never thought possible and I’m still learning, even if I don’t yet play as well as I’d like.
I also found a class through our local community college. I didn’t learn much from class itself, but I did meet a few people to play with. I even participated in a Christmas concert with the group - my first public performance! Be aware, though: each of the folks I’ve met have different personal goals, and most have fairly strong personalities. I’ve chosen to interact as “the new player” and follow their leads even though they go in directions I personally wouldn’t choose. It’s interesting!
