I view this book as the training wheels of self-help books. This book's intentions is to teach us how to consistently turn our good intentions into action so that we can be as successful as possible in the work we do - however it doesn't quite get to good stuff until halfway through the book.
If you are struggling to get things done and are finding yourself procrastinating - this is a solid book to read (but I'd start in the middle of it to jump straight into the meat of how to change our behavior!).
