If you take away one lesson from this chapter, it should be that few practices will improve the quality of your attention—and the size of your attentional space—more than meditation and mindfulness.
I could sense the book building to this point but it took a very long time actually doing that. Hyperfocus sounded way to much like meditation and mindfulness. Makes me wonder if I should have focused on those two rather than reading this book. But I will stay with the book till the end before declaring so with confidence.
