I had indeed heard of mindmapping and even seen the amazing results of a colleague who has mounted his stuff and hired 6 employees .... But I did not know where to take it! the book is crystal clear, I read it thoroughly two evenings where I really am not sleeping on the book, I simply put aside arriving in four-color cards which we can (must !) draw ... the book gives particular pins mindmapping, grammar somehow, like turning in the direction of clockwise starting at noon, highlight the important and urgent in pink yellow and when it's the two it becomes orange, use it to take notes efficiently, and logic PERERV (pronounced Father Hervé) with phases Prepare, Evoke, Branch out, Examining, Reorganize, Watch! and a few other tricks that I let you discover ... its analysis of additional software is an uncommon finesse. Bravo and thank you.
