This is what Shakespeare has to say about it:
…[T]he fixed sentinels almost receive
The secret whispers of each other’s watch.
Fire answers fire, and through their paly flames
Each battle sees the other’s umbered face.
…But I think we can do better. How about Churchill?

Who painted the sky? You did. Who brings the sun up over the horizon, every day? With a fresh breeze, just at the darkest time of all? It is only necessary that you see it. We spent every day of that flight praying for more light. The dawn is your responsibility, every single day: Your only duty is to wake up tomorrow.
This isn’t going to make much sense, but I didn’t know how much I needed to read that until I read it, you know?
