A book that has been eye-opening and life-changing for me is
“Taming your outer child” by Susan Anderson

This book really helped me recognize the times that I do things that do not serve me and help understand underlying emotions and fears driving poor behaviors and be able to address them personally. Without this concept I don’t think I would feel nearly as ready to take on this program.
