This is a great, short guide on improving your focus and time efficiency. As someone who works very long hours and is constantly balancing that with family, this is a subject near and dear to my heart - and this book was worth the read.
Many of these tips are common sense, but it helps being reminded of them. Other tips have links to various scheduling and time management tools I was unaware of. The author also knows what he's talking about. I especially agree with his conclusion that multi-tasking is not efficient; and the power of saying "no" to certain tasks sometimes is something I think of lot of us need to be reminded of.
I also like the fact that the book is short. In a word, it's focused!
