I'm halfway through my life, and as far as I can tell, the real lesson of the past isn't that I made some mistakes, it's that I didn't make nearly enough of them. I doubt I'll be lying on my deathbed in forty or fifty years, congratulating myself on the fact that I never had sex in an airplane with a handsome Italian businessman, or patting myself on the back for all those years of involuntary celibacy I endured after my divorce. If recent experience is any guide, I'll probably be lying in that hospital bed with my body full of tubes, sneaking glances at the handsome young doctor, wishing that I hadn't been such a coward. Wishing I'd taken more risks, made more mistakes, and accumulated more regrets. Just wishing I'd lived when I had the chance.
