Great advice to browse in the library. Their job is to make reading seem fun so they can make a lot of suggestions or offer lists or displays to draw you in…they know what people like. Also a lot of public libraries have book clubs or meetups, it can help to have that kind of light social pressure to finish a book, and you will learn what other people have to say, why they think something is really good (or not), it can open up your mind to new things to look for when you read.
