Book for March

Hi ladies, I hope it's not too early to decide on the book for March.  It has been really hard for me to pick something.  I would like to choose, The Happiness Project, by Gretchen Rubin.  I am reading it now (along with Precious Bane (sooo good!)) and I really feel like this is the book I'm supposed to choose.  If you have read it before for Book Club, let me know though and I will choose something else.
