Rough, inconsistent, and somewhat outputting
Mr. Metivier' s enthusiasm for his subject is obvious. But, and this is a very big BUT, if he wishes converts to his method, he badly needs a good editor. This book was not ready for publication, and it looked to this reader to be of the "first draft- last draft" variety. This very brief book, which does have some helpful content, is riddled with spelling and grammar errors. For example, the author makes much of the memorization of the sequence of a deck of cards. Several times the printer used "suite" for a "suit" of cards, and then switched to the correct spelling later. Grammar errors appear with jarring frequency.
I like the ideas contained in the book, if not the implementation, which demonstrates that we all have minds that work differently.
