Like a patient with a terminal disease, knowing that we will die can cause our love for the world to broaden and deepen. Knowing that our relationships won’t last forever can cause us to cherish them even more. And what do we do for the people we love and will lose? We try to deepen our connections with them in the time we have left. We try to lessen some of their suffering and increase some of their joy. And we consider what will be our lasting mark on the world.
