just my 0.0005 cents but I think I only read 1 novel (not even, it was a play) apart from my set texts this year oops, last year
I found that it was easier to expand my vocabulary by reading newspaper-like articles about world issues etc, but I guess it depends what you're interested in. Also, this may seem like the wrong advice but I also learned a few new words from TV shows and movies (but again, it depends what you watch)
High quality essays (heaaaaaaaaaaps on AN) are invaluable in helping you improve your vocab and expression without even realising it.
I'm a bit of a closet nerd so something I picked up from my brother was to add unfamiliar words I heard or read to a list on the notes section of my phone, look them up, learn them and vow to use them at some point in my work. Never regretted it.
