I do not believe that you become a successful leader by JUST reading a few books on supervision, by JUST attending a supervision school, by JUST attending current training courses in supervision, by JUST working in the field, or by JUST listening to those above you, around you and under you. NO, you become a successful leader by doing no less than a combination of ALL these things. If you are a supervisor, read this book and self-reflect, if you are going to be a supervisor, read this book and start to think like a leader now.
