The pyramid principle

Great logic ideas how to structure your notes, mails or long essays! However language used and complicated examples given to explain ideas make getting the concepts very frustrating.
The book describes very good basics how to structure your ideas – starting with story telling concepts, putting ideas first, applying pyramid concept to summarize your points and support main ideas etc.
On the other hand the author loves using not frequently used words and jargon combined with excessive use of passive voice. This makes comprehending the ideas very difficult, especially for me, non-native English speaker. On top of these difficulties, examples used in the book are mostly way too technical that just understanding what is it all about completely distracts from absorbing the idea. I think if the ideas of the book is targeted to general public, language and examples should be so understandable that the reader easily focuses just on the main concepts.
In summary, the book is full of great ideas very useful for any writer. Just the difficult wording makes you re-read the text couple of times to get to the roots.
