My original Course with Time Manager International, of Denmark in 1987 opened my mind to this concept using Tony Buzan's trainers. TMI had a revolutionary management methodology and were then agents for Mind Map Training. This was part of their organizational training system based on Key Areas and the "Daruma Doll" principle. There is no better presentation of this mind mapping concept other than by Tony Buzan himself.

Tony Buzan's 10 rules hold true and many software packages do not adequately reflect them particularly in the use of straight lines. However rules are made to be broken and different people like different features to suit their application.
