Let me therefore live as if every moment were to be my last.

Living with the shortness of things in view is less about urgency than about attention. Taken literally it becomes an excuse for recklessness, which helps nobody. Taken steadily it does something smaller and better: it makes you reluctant to leave a conversation badly, or to spend an afternoon half-present in a room with people you love. The knowledge does not need to be dramatic to work.

You might pick one thing you have been postponing because there is always more time. Say it, send it, or go. Not because the end is near, but because postponement has a way of becoming permanent without announcing itself.
