The majority of the reviews seem to focus on the reviewer's feelings: towards the author, his previous works, "it was too simple," "too complicated," "repetitive," and so on. However, if you're not familiar with mind-maps (which are creative techniques used to organize thoughts, identify key ideas, link themes, and remember more effectively, while using the both sides of the brain), you might think of it as a gimmicky New-Agey concept without practical applications. In other words, not useful, interesting but not useful. I'd just like to give personal endorsement. I've used mind maps for about twenty years to organize engineering projects at work, remember books I've read, identify daily goals, learn chess opening ideas, outline papers I'm writing, and identify the important from the trivial. This book does have flaws in that Buzan has already written it in his earlier works, and the title suggests to more impressive results than can be delivered ("maximize your brain's potential"). You won't become a genius, you will still have to work at thinking, you'll just have an additional tool to help you. Mind maps are fun, easy-to-use, useful ways to organize and retain information and generate ideas. Linear notes just don't jog the memory. It's still amazing to me how a hastily drawn mind map on an article, book, movie, lecture - a map I'll scribble with stupid little drawings and doodles and throw away days later - can help me remember so much years later !! It works. I use it. It helps.
