If you are someone who is new or has a basic understanding of habit forming then I definitely would recommend this book to you. If you are someone who struggles with making goals and creating habits, I would also recommend Atomic Habits to you. 

Atomic Habits does an amazing job at breaking down habits and giving you instructions on how to start small and think about creating habits in your daily life. It gives great tips on how to consciously think about habits and how to put your mind to accomplishing the habits you set.

That being said, I do agree with many of the other reviews in the sense that this book is not ground breaking nor does James reform the wheel on creating habits. He just gives a better understanding on habits than most books out there. He also uses a lot of fitness and health culture examples, which I understand since 1)easy to write about and 2)statistically the highest habit/goal set every single year, but still it get's annoying and quite repetitive. Finally besides a few tips there really isn't anything that we all have not heard before - start small, build on your habits, and don't expect changes overnight. 

All in all it was still good and I still found a few things I didn't think to try in my own habit building.
