This is a mindfullness meditation guide in disguise. It is clearly geared toward "down-to-earth" readers (being written by an early google engineer), and stocked with references to neuroscience and psychology studies.
That still leaves open the debate about the validity, relevance, variety and trustworthiness of the sources - which I'm unfortunately quite unequiped to tackle. I don't know if the book has had to be debunked.
And I would not blame anyone for the "Google Kool-Aid hipster zealot fad" gut reaction ;)
I do understand it can be annoying when they are presented as some kind of absolute truth though.
I can recommend the material in "Mastering Your Hidden Self" by Serge Kahili King (1) as a very good way of working with various unproven-but-reported-effective-by-some techniques without being required faith.
