No one asks to be born. And no one wants to die. We don’t bring ourselves into the world, and when it’s time for us to leave, the decision will not be ours to make. But what we do with the time in between the day we are born and the day we die, that is what constitutes a human life. You will have to make choices—and those choices will map out the shape and course of your life. We are all cartographers—all of us. We all want to write our names on the map of the world.
