wodfest: "A Sheep Falls out of the Tree" is a terrific book. I owned "Memo" for ages but when I first purchased it I read the first 65 pages then put it down. I went back and re-read it (all the way through) after being re-inspired by "Walking with Einstein" about the weird and wonderful world of memory championships. so "A Sheep Falls Out of the Tree" one was sort-of the 3rd in a series of books. I still haven't mastered the master system but I certainly will be trying to. I think the advice of "Memo" is stronger than this book but I do think that this book is better for learning the master system and it strikes me that I will find that very useful in the long term. Highly recommended for anyone wanting to improve their memory and who isn't interested in being subjected to a lot of claptrap (aka hokum) about it.… (plus d'informations)
