I've been working from home for 20 years, so it's not a big deal for me. But I miss my walks outside and I spend too much time sitting in front of a computer, which makes me hate the idea of also sitting at the piano right now.
Recently I've been listening to a lot of Mozart, because I had this crazy idea that I might try and learn an entire sonata - K. 280. I kind of learned the Adagio, and now I don't think I have the patience nor the technique to learn the other movements, but it was interesting to read and analyse a sonata in its entirety.
I'm also listening to all Chopin's nocturnes, because I'm learning no. 20. I must say that I find it easier than no. 21, which I learnt last year - probably because that was my first. But I can see that the musicality, smoothness, and expression of this one will be harder.
I feel that learning any sonata is mammoth endeavour. So you're not alone. In 10 years, I only managed to learn 2 sonatas, revisited them a couple of times and I'm still not any good at them.
I've attempted 3 nocturnes so far, Op. 27 No. 2, Op. 72 No. 1 (did this for AMEB grade 8 exam) and Op. 48 No. 1. I occasionally feel like I want to return to Op. 27 No. 2 but never got to it. As I flip through the book, there's so much more to learn here but I feel obliged to explore outside of my usual composers, and Schubert has been on top of my list of next 'get to know' music.
