Query: A little reminder can't hurt...

I agree with those who have given this book a poor review, in that, there really is nothing in it that you don't already know. However, I disagree that it is a waste of time to read. It is very easy in today's busy world to forget what you already know -- and that is that change happens. Yes, change happens every day and we are constantly dealing with it. However, sometimes it is easy to get stuck in a rut and resist change. If being conscious of a problem is half the battle, then how can this book be all bad? It definitely raises your awareness of how change affects all of us and provides simple ways to deal with it. I won't say it's the best book I've ever read, but it's definitely worth the 30 minutes it will take you to read it.
