I started playing piano in 2018 and now it's part of my daily routine. I would recommend this to folks how are looking where to invest time to. Mastering an instrument takes years, but it's progress and dopamine.
Same here. There even is some progress (there should be after this much time invested, but this is easily the hardest thing I have tried to master in my life and I'm already resigned to not ever getting as good as I would like to be). It's a lot of fun too!
