The Happiness Project by Gretchen Rubin was also a life changing book that I will most likely re-read this year. The LA Candy Series by Lauren Conrad was my guilty pleasure series. Not going to change your life or anything but will provide you with some solid light entertainment. I also really liked Is Everyone Hanging out Without Meand Bossypants, like the rest of the world.
I am taking recommendations for books to read in 2012, so comment away with them. Anyone know of a good book on Margaret Thatcher? I saw a preview for The Iron Lady movie about her and now want to learn more about her.
