Very easy to read this book and growth mind. There are no abstraction here. Very pragmatics. For those who want to know/understand Stoic. I'm highly recommended.
As a newcomer to it, I found this book extremely helpful and instantly impactful to my daily life. That said, I find that you need to keep up the practice continually as its impact has a half life and fades over time.
I can see why many would dislike this book vs. the sources, but it definitely makes the overall idea more palatable. Reading the Meditations isn't for everyone.
