For me, it was easier to branch out a little bit because my go-to genres are Fantasy/High Fantasy and Historical Fiction, with a smattering of Classics (almost any genre.)

When I want to get out of a rut, I started with baby steps - so, instead of Historical Fiction, I read a Historical Romance (by an author my friend, who has a similar background, likes/dislikes, and sense of humor to mine, recommended; I figured if she'd enjoyed the books, I was more likely to enjoy them as well); instead of a Fantasy/High Fantasy, I tried a Mystery with Fantasy elements; etc.
