“Most of us look forward to the day when our identity hardens, like a cast protecting against life's dings. When we're younger, we yearn for the moment when we'll be fully formed and have life figured out. Maybe it's when we find love, or have kids, or write that book, or retire. And then we get older and realize that moment never happens. You're never done figuring it out, but hopefully you're better equipped to tolerate not knowing.”
