This was surprisingly good. It isn't about what the title makes it to be. I feel like the book could be summed up in a few lines or pages, but I can't think of a way to write a summary which will have any impact at all, or not sound like generic wise sounding advice. So, at least in that way, the summary of the book will be like a zen koan. You need to have thought about it, meditated on it, and then finally reached an understanding of its true meaning (at least that's how I assume koans work).

The author talks about things that everyone must already have had thoughts about, but he has a clarity of thought that makes it feel like an enjoyable and deep conversation. The book is also surprisingly radical; it does not really promote 'time management tips / tricks / techniques' that will make you more productive at finishing tasks at your job, for example; not directly, anyways.
