I really enjoyed this book. It taught me many valuable lessons that I still use today. Unlike so many business and self-help books the conclusions presented in this book are based on research, not psycho-babble.Is it a bit dry? Sure. But here's what you get for patiently studying the concepts: If you are serious about getting along with others, at home and at work, this book can help you develop advanced interpersonal skills that will serve you for a lifetime. That's value.For example, the accountants and engineers at work used to drive me nuts with their demands for more and more detail, numbers were all they cared about. I'm in Marketing so I'm easily bored. I'd become frustrated, "Why can't they (my co-workers) see the larger picture? What can't they connect the dots, it's so obvious?" I found many people to be tedious, short-sighted, unwilling to make decisions and, most importantly, act! I even considered some to be a bit dim but I knew that was wrong, these were smart people. My wife sometimes fell into this category too. Yikes! I'd struggled with this for most of my life. So what's the deal?Here's where this book really helped me and, in a way, changed my life. What this book taught me was these "types" of people were what Merrill calls, "Analytical." They just processed the world differently than I did. I think strategically and am a "Driver." I can take a bit of information and usually extrapolate the most likely outcomes. As a teacher once told me, "you anticipate well, you can see around the corner and most people can't." Some people need to see the evidence before reaching any conclusions. That's not a bad thing, in fact it's a good thing. I don't want my doctor, or my wife, jumping to ANY rash conclusions, something I've been known to do.This book taught me to be more patient, to better understand we're not all alike, and to both identify and communicate better with those who are different than me. And it did so in very specific terms. These are valuable life-lessons that I use each and every day.I hope you get as much out of the book as I did.
