I bought this book mainly out of curiosity. I stumbled across the Bullet Journal method in October 2017 and found it increased my productivity, motivation and focus. I was an immediate fan and studied everything I could find on the topic. Hence the reason why I hesitated to buy the book as I didn’t think there was much left to learn. I am very happy I did buy the book and read it. The Bullet Journal method explains the thinking behind the method and it was insightful to read this in The words of the father of the Bullet Journal method. The best review I have to offer is that I was sad when I came to the end and found myself paging even through the index. This does not often happen when reading a nonfiction book. I found it riveting. Thank you Carroll Ryder.
