I usually try to read around 50 books a year. When I finally counted up properly the other day it turned out I hit 64 last year, which is surprising given that I started doing a Master's degree part time last year. A lot of that was probably down to procrastination, so maybe it's not so surprising after all.
I like to keep track of the books I've read so I can come back to authors I like, and remember which book in a series I'm up to. I include audio books and graphic novels.
Sometimes I try a reading challenge, like the Pop Sugar Reading Challenge. I've never actually managed to complete it, but it's fun.
