This book was a bit too rich in stories and a bit low when it comes to structures knowledge and advice. I kind of got used to these types of educational books to have a lot of fillers, but perhaps it felt like a bit too much for me at this time, or perhaps just many of the takeaway messages were already known to me, so I did not feel I learned much. If you're new to the topic, the book is well written and has a nice flow of the story, so it's not at all that bad.
