How to Take Smart Notes  (English, Book, Ahrens Soenke)

This book solved so many unsolved mysteries. I am grateful to the author. Although the book not bulky, but it is research-heavy. I wish I could have read this book much earlier. This book is not only about note taking, the traditional way or otherwise. It is much more than that. It is about developing cognitive ability, thinking process, understanding, elaboration and developing mental models.
