This book most certainly discusses an interesting concept and way of approaching clients and the issues that they bring to therapists and coaches. The use of challenge as a change process is not new but Mr Hollander's book shows you how to use challenges in a much more direct, yet with humour, manner. This book is a blow-by-blow introduction on how to use this approach in your practice -” whether you're a coach or therapist. The demonstrations within its pages really help you to understand how and why this technique works. It is a book that is well worth reading.
