While the book is interesting, it doesn't feel too original. Whereas books like Stolen Focus by Johann Hari include new nad interesting interviews with world-leading experts, this is mostly based on anecdotal stories which makes it less interesting (why would I want to be told about Kirk Hammet from a subjective viewpoint when I could have a journalist ask though-provoking questions to a world-leading scientist) and also less informative; it feels more like one is trying to repeat the same idea enough times for someone to believe that it is the objective truth.

However, this book is still a book worth reading and far from the worst of the self-help genre. There are many small notes I've made myself while reading this book, and I do have some main takeaways unlike other books where I struggle to find more than one minor takeaway.

I'd give it 3.5 but I can't seem to figure out how, so 3 it is.
