André Aciman said this quote

Most of us can't help but live as though we've got two lives to live, one is the mockup, the other the finished version, and then there are all those versions in between. But there's only one, and before you know it, your heart is worn out, and, as for your body, there comes a point when no one looks at it, much less wants to come near it. Right now there's sorrow. I don't envy the pain. But I envy you the pain. (p. 225)
