This is a book of two halves. The first half which concentrates on Hyperfocus is excellent. It is packed full of good thinking and practical tools that are very useful. In fact as a coach I have recommended this book to several of my clients. The second half of the book is about scatterfocus which is about developing innovative thinking. I didn't find this particularly engaging and there are much better authors on this topic. Nonetheless, the first part is so good, I would still recommend buying even if you did as I did - give up half-way through.
