I enjoyed Alise Cortez's book immensely and found great inspiration in many of the stories she includes.
I think there is a time in everyone's life when this book will resonate and strike home.
There are videos and worksheets to accompany the book, so if you give it time then the book will have more reach within. I certainly found more depth and interest in doing the activities and giving it some reflection time.
I admit however, whilst I completed the book, I didn't complete all the activities (yet). However, if you're serious about this area of your life: do them! I'm sure they will add value.
