While I haven't fully covered this book, I'll set a break to reading it (and listening to the podcast), so it's a good moment to add it and recommend it. I really like the simple way of introducing important topics - the examples chosen, and angles taken - and while sometimes I find myself at odds with some interpretations (I sometimes disagree with people writing books, I'm that kind of person), I always find his viewpoints intriguing and sincere in his approach.

Listen to the podcast, read the book. It's useful, it's interesting, it's a good introduction. But don't settle for just this book. If you go for this, and not dive deeper into the topic, it's a bit of a shame - you're losing nuances and the possibility to write a review in which you disagree with the author, but agree that he did a great job.
