There are people for whom this book will be an excellent starting point for isolating their goals and tactics and achieving that they want. (Indeed, one of my colleagues, whom I respect for her tenacity and ability to set and achieve goals is the one who recommended this to me.) I am not one of those people.
Perhaps because I read so much about time management and productivity, there was nothing novel here for me to explore. I don't disagree with any of the content so much as I didn't find it to be particularly helpful for my use personal use case, nor for most of my clients. The truths told by Moran (and his co-writer, Lennington) permeate the book -- getting rid of a victim mentality, seeing accountability in terms of "ownership" of one's obligations rather than the consequences of achieving or failing to achieving them -- these truths are all valid. However, I suspect that only the very ignorant, the very young, or the very self-unaware would not recognize the general truths described in this book.
Every paragraph seemed to find me talking back to the authors, "Yeah, of course, but what are you going to tell them to DO about it?" Perhaps because so many of my clients suffer from depression and/or anxiety disorders, my concerns about this are more heightened, but I kept saying, "the people who need your advice CAN'T just say "I'm going do to this even if my feelings tell me I don't want to" because they literally, without intervention, cannot." Perhaps Moran fails to recognize how pervasive depression is in society and how depression, anxiety, and executive function disorders are the reason why people need books like this purport to accomplish, but why books EXACTLY like this don't work.
The central conceit is that instead of making yearlong goals and plans, you should isolate what you want to accomplish in tight time frames of 12 weeks. This prevents all of that wishy-washy laziness (my words, not the authors') that let us let up. So far, so good. Then, identify up to three main goals, and the specific tactics you will use to move yourself forward, each week, toward your goals. Next, measure those achievements, identifying lead indicators (what you DO, like making sales calls) and lag indicators (measures or signs of achievement, like winning contracts), and focus that active, strategic use of metrics to redouble your efforts and track where you fall by the wayside. Fine. Dandy.
Except, as a professional organizer, I know that these instructions are merely window dressing. Most people who have trouble achieving things don't have issues with creating plans, but executing them, and then have trouble executing because a) they do the wrong things for the right reasons or b) they avoid doing the right things (for mostly the "wrong" reasons). This book will work fine for people who have trouble creating frameworks of what they should do, and the concepts are helpful for people who don't pay attention to their metrics.
Basically, you are supposed to do 4 things: Plan your week (and, one assumes, do what you planned), score your work (what percentage of your goals did you achieve?), and have a weekly accountability meeting (WAM) to give yourself a reality check. Yay. Rah.
Unfortunately, I find most people don't do stuff, not because they don't know what to do, but because "they don't really wanna." And there's just not enough here to conquer that. Yes, near the end, there's a chapter with focus on other authors' books, like Duhigg's The Power of Habit or Chip and Dan Heath's Switch, which talks about the psychology of change, and throughout the book, Moran and Lennington push the idea of commitment to one's goals and near the end almost get into some interesting and helpful material on conquering one's hidden intentions. But it comes too late, and there is too little.
Mostly, this book sets up a framework (which seems designed to sell Moran and Lennington's web-based service-oriented coaching business) and then sets out, in an incredibly repetitive manner, to hit the same points. The book would have been (and probably was) a series blog posts, and I think I might have found it less annoying that way than as a full book (though I don't begrudge anyone from making money from creating a book like this).
I also found the book to be painfully, paint-dryingly, boring. There are a handful of earnest anecdotes about how clients (and their young adult children) have put the precepts of the 12 Week Year into place, but there's not the tiniest degree of humor in this earnest tome.
A friend pointed out that "Get It Done" is more about identifying what needs to be done than execution; The 12 Week Year is certainly more about execution than identifying what must be done. The problem, which may be more systemic in humanity than just in self-help books, is that there's a vast psychological and motivational chasm between knowing what to do and actually doing it, and this book fails to bridge the chasm.
I should note, this is not a "bad" book, per se. None of the advice is flawed, in and of itself. The guidance for designing an effective weekly schedule, for example, is not much different from how I'd advise someone (though the book seems to really be targeted for upper-middle class, white collar knowledge workers and executives and not solo professionals with small children or elderly relatives for whom they care, or basically any aspects of their schedule over which they don't have mastery and decision-making prowess).
If you've never read a book on produtivity or time management, don't start here. If you've read tons, this won't hurt you. I'm just not sure how much it will help you. If you're great at follow-through but just want to try a new framework to tighten up your response time and keep yourself accountable and committed, this may be your book. But I know it wouldn't be right for most of my clients, and it is not right me.
