Yes, AO is really good. I loved that it was free and well organized. I even went to an AO conference years ago when they had it in my state. All of the founders spoke at it. It was really interesting and motivating. Those books only get more expensive! Better to stock up now or plan to check out some from your local library if they are available! We do year round as well, but we take off every Friday because life is too crazy on Fridays around here!
