So far I have only been about a quarter into the book, and I would say I am liking it.

I have read another book earlier on this same topic - "In Praise of Slowness" by Carl Honore, which is a more formal, evidence based treatment of the subject ( as almost all popular science books are) - while this book by Haemin Sunim is a more informal approach, and I'd say based more on the writer's experience.
