3.5 — overall, I enjoyed this book. It’s quick and straight to the point. Some topics/chapters were more interesting to me than others and I liked the research that was presented. I feel like I could’ve liked it more if there was more in each chapter - the author gets her point across, but I expected more detailed dives into each chapter & feel like it could’ve blossomed as a longer book. However, it’s not horrible that it’s concise and I still liked learning about what I was reading.
