As a belated birthday present, from him to us, Leo Babauta, the writer of the blog Zen Habits had written a book titled ‘The Little Book of Contentment'.
He said it on the beginning, that this book is only for people, that are ready to spend the hour reading. It is not a book, to be put aside. It this case, it is better to not even think about it (since you can end up feeling guilty or bad for not reading it).
Since the book have a small amount of words per page, and it is only 111 pages long, it is a quick read, and suitable, even if you do not have a lot of time.
It this book, he uses the simple, but extremely friendly writing style, to outline the root causes of the non contentment with ourselves, the feeling and the effects, that we get from not being content. He uses the short anecdotes, that illustrate the different points and are easy to relate to.
The chapters themselves are extremely short, and can be read separately. More like blog posts, easily digested and easy to implement. To make it even easier, he added little exercises on the end of every chapter. But as the book continues through to the end, there are more and more practical advice inside the chapters as well.
The exercises are really simple, and they seemed effective (I only read the book today), and most of them take less than a couple of minutes. Most of them can be done on the toilet, if you have no other time, since they only require thinking. Or they are exercise, that only require awareness, like noticing when you are jealous.
As I mentioned, the style is simple and extremely friendly. He uses questions, to illustrate the points, along with the stories. He tries to make us think, by reflecting on ourselves and seeing our situation.
He finishes the book with the frequently asked question, that explain some of the most common obstacles, that can come our way when trying to be more content.
It is a great book. It is easy to read and really understandable. But the simplicity does not hide the non logical components. I didn't notice any contradictions in the book.
