Back before the Peloponnesian Wars, when I still believed that men were kinder than horses and that other people held the instruction book to life, I had an encounter with the little gods of the self-help genre -- call it an anti-epiphany -- that I now regard as formative. I was in my mid-30s, old enough to be smart but young enough not to bother, and someone had dashed my heart upon the well-worn rocks of betrayal. I was nonetheless pretending to carry on, and so one morning found me sitting in a heap on my living room floor, surrounded by piles of damp tissue and stacks of incoming books from publishers. Usually the self-help review copies went straightaway to my favorite retirement home (where no one needed them any longer) or neighborhood library (where at least the advice would be free). But that day I was an easy mark for fortune-cookie insights. That day I would have believed the UPS guy if he'd been willing to listen -- he wasn't; I tried -- so I opened one up and began.
