I bought this book, written by Rolf Dobelli, on a whim while browsing in a book store waiting for my wife. The subject matter looked interesting and the praise for the book was convincing.
Mr Dobelli would have likely detested my purchase decision, since it was rather impulsive and made purely based on praise that was clearly put on the book cover to sell the very same book it praises!
The book is ninety-nine chapters long with each chapter no longer than three pages, making it quite easy to read and consume. Alas, because of this - the bite sized nature of the chapters - it took me much longer to finish reading this book than it would normally take me to read a book of similar length. Maybe because it gave me a false sense of fulfillment completing a few chapters a day when in reality I had read no more than a couple of pages.
