Just received my first mini!!! I really love the workbook. The online Facebook group is also great everyone is very active and super nice which I was hesitant about. Dr. Sarah is very involved in the group which is nice to see. I like the concept of the workbook and hope to really get the most of it not just this month, but try to carry these methods all the time. I also received challenge cards which I enjoy doing daily. The workbook is easy to finish in one sitting, but can be broken up to do grouped sections weekly. I will also say the shipping is pretty fast, compared to some boxes I get.
