Just by chance I came on the mind-map and the concept was immediately seduced and I also deepened through this first book and Xmind software ...

The concept pleases me as much and tjrs ds some situations it already brings me a real contribution for fairly simple problems but moreover I embrouillais me some brushes ... The book, I think, could have been a little more practical and dissect real cases from A to Z. I do not despair, perhaps, to find such a book that would further deepen this concept, in the hope that this concept is really convenient for complex cases ... To be continued ...
