Socrates said, “The unexamined life is not worth living.” That may be an overstatement, but it’s certainly useful to examine the way you live your life and consider how to improve it. I didn’t get around to that until I was almost eighty years old. Then I really went at it, giving a lot of thought to major decisions I’d made. Why, I wondered, were some of them so wise and others so stupid?

After sustained study and analysis, I concluded that there are just three keys to making consistently wise decisions. I set them out in my book All It Takes, the Three Keys to Making Wise Decisions and not Making Stupid Ones.

This book is not an abstract tome or inspirational advice. It’s one hundred and fifty pages filled with examples from life, history, literature, and research psychology and distills the wisdom to be learned from them. I think you’ll find something valuable in it, maybe something that will make a difference in your life.
