This book will change your life. I had already read their blog from start to finish before I read the book. But the book does provide some new material which is great for anyone who loves to blog. Also anyone who hasn't read the blog its incredible as its sums up a lot of stuff making it very understandable. I reckon this is also good for people introducing themselves to FI, but also incredible for people who understand a lot about it. I also feel like I get to know Kristy and Bryce a lot more as they talk a bit more about their background and life as well. Overall, I highly recommend this book to everyone even if you have never heard of FI.
