I think how utterly this last decade has changed me. When I look at what my life consisted of before middle age, I see almost everything has altered. Then, it was all babies, wine, and a certain fearless, idiot blitheness that I enjoyed at the time but am glad has now passed. As you get older, you just are a little more traumatized by life, to a greater or lesser degree. You are aware how precious and perilous life and happiness is—you know everything can change in a second, with a fall, or a phone call, or a news flash—but because you have survived these things, and had your fluffy blitheness rubbed off by life, you are also ready to deal with them.
The strength of young blitheness comes from an ignorance that things will, absolutely, go wrong. At some point, the very worst thing will happen—but you do not know that, yet. You enjoy feeling unbreakable.
By way of contrast, the fearlessness you have now, in your older years, is the knowledge that, whatever happens, and however hard you inevitably break, you will live through it—one step at a time. And as you become tougher, you simultaneously realize how fragile other people are. You are gentler. You are kinder. You automatically presume everyone you speak to has a secret soreness or sorrow. Because, almost always, they do.
But once a crisis has passed—once you enter into a period of peacefulness—what are you to do? You are like a demobbed soldier; a retired assassin on a beach holiday. A former prime minister on the bus. You have all these new powers—and nothing now to do with them. The cogs are whirring, the adrenaline is still up—but what are you to do without yourself? This is the moment in your life where there is a sudden space, and silence, where you have to ask yourself: What is my purpose now?
