Mind Performance Hacks is much more than a "hack" book. I didn't expect to read all of it since you normally only read the "hacks" of particular importance to you at the moment.
I did read the entire book though because it was so fascinating and helpful.
The first chapter was somewhat of a disappointment since many of the memory hacks only fit with a natural ability for visual or musical talent, which I don't have. And 1 or 2 of the hacks were so complicated that you'd have to need to memorize a huge volume of material to make it worth while to work hard at the hack to get good enough to find it useful. This is certainly not the
fault of the author since he was only letting you know about the hack.
But I loved chapter 2 on information processing, especially the map your mind hack. I've done mind maps before but this book mind it more "how to" to really assimulate the information. It also had a hack for speedwords that looks very useful which I hope to implement soon.
The Math chapter was also helpful if you need to develop more of a "feel" for numbers and get to an
approximate answer quickly.
The book has a nice format. Each hack starts with a brief overview. Then the In Action section explains the details. Then the How It Works section explains how your brain is using the hack. The In Real Life section gives an example of how the author used the hack. Finally, the hack ends with lots of external references to web sites and other books.
I highly recommend this book to anyone who wants to have a non-technical understanding of how their brain works and how to get more out of it. If you are a creative person and need to get more out of your thoughts, this book is for you. If you are an analytical person and need to make better decisions or be more intuitive about numbers, this book is for you. If you are just curious on a few hacks to have better recall, this book is worth getting. I bet you end up reading the whole book, like I did!
