Yes, but it's mostly because I love making lists and less because it's actually of any use. I frequently go off-list and don't feel bad if I don't get to a book I originally had on my list and end up reading other things.

I do find this sometimes helps me commit to actually reading some classics that are on my TBR but I'm a bit intimated by for whatever reason, though. The classic I'm determined to read this month is Great Expectations.
