This book was incredible. I'm a person who is pretty much obsessed with personality tests and self-reflection tools and self-analysis, so I absolutely devoured this one. I have always been awful at creating good habits and breaking bad ones, and this book was incredibly enlightening as to why that is. It gave me so many solid insights into my personality and how to play into my strengths to create solid habits that I will actually keep...it's just an excellent resource that is full of research and practical, manageable advice but reads easily. I haven't read anything else by Rubin, but now I want to read EVERYTHING. This book will absolutely be one I refer to over and over as I keep growing and learning!
