@Helen50@bookstodon The thing that made me better at abandoning books was reading Sarum. It's over 1,100 pages and tells the story of five families from pre-history to 1985 in the area around Stonehenge. While it had its moments (who doesn't like Stonehenge?) most of the book was incredibly tedious.
I slogged through it as a teenager - I'd started and by damn I was gonna finish! I got to the end and... it really wasn't worth it. I decided I never had to finish any other book I wasn't enjoying.
