Team building we build through our experiences, meetings, lectures. This book help to enrich my knowledge in this area but also to think about new approaches in a benevolent spirit. I experienced there is little new approaches and group cohesion particular techniques described in the records synthetically and sufficiently precise to be directly applicable. These exercises and animation upstream councils have contributed to the success of my seminar. Kudos to the author for this very useful work for experienced or occasional entertainers.
