I had your same kind of problem, or more like just not having any kind of robust interest in art, and I was living in Amsterdam for a while which of course has great art museums... I also didn't have an internet connection at home nor a smartphone, so it was really easy to build new interests, not being dopaminergically tethered to the world wide web... So I decided to get a "museumkaart" which is a cheap way for residents to get endless museum access for a whole year, and to write a little journal about a museum every weekend. Because I'm a kind of obsessive personality and I didn't have anything else to do I ended up reading quite a bit of whatever relevant stuff I could find to flesh out the journal entries, and that's why I read the Van Gogh letters! So yeah, I also recommend finding a way to be more disconnected from the internet on evenings and weekends. :)
