The author's boasting is something I can imagine bothering some people! He definetly has a big mouth and the book beeing an american style writing doesn't help either. (especially at the end the book transforms to the longest advertisement in history for his own company).

But if you can look past that there were a lot of practical take away in the book, at least for me. The largest was how should I think about negotiation and how it is a part of life. My favourite technique I still use from day to day is 'labeling' and 'false labeling'. It just helps naturally start conversations when you meet someone at the office coffee machine.

Anyone who has mental blocks asking for a raise should definetly read it.
