You should know up front that his book might cause you to reevaluate your life. It might influence you to quit your job and switch careers. You might start to look at your relationships in a different way. Hell, it might even cause you to realize that you're not in a good marriage. That's not just hyperbole, either. T. C. Luoma's popular weekly column-the best of which are featured here in The Testosterone Principles 2: Manhood and Other Stuff-has elicited exactly such potentially life-changing thoughts from the people who regularly read his work. He doesn't preach or rap you on the knuckles. Instead, he shows you glimpses of what life-your life-could and maybe should look like. If you've got even a speck of self-awareness, you end up asking yourself, "Hey, is he talking about me?" His observations, liberally backed up with science and spiced up with quirky references to popular culture, serve as a guide to the weird, conflicted, often horribly flawed creature called man.
