““It occurs to me now that we mostly live facing “forward” – toward the future. Goals stretch away before us; we reach them one by one, as if driving down a highway. We glance into our rearview mirror now and then, but we don’t truly look back until the journey’s ended. And then, of course, it all looks different. The road curved and rose and fell more than we realized. The sequence wasn’t half as tidy as we thought. Looking back, we see something complex but also strangely perfect. We see something completed.””
