A classic Marcus quote:

“At dawn, when you have trouble getting out of bed, tell yourself: ‘I have to go to work — as a human being. What do I have to complain of, if I’m going to do what I was born for — the things I was brought into the world to do? Or is this what I was created for? To huddle under the blankets and stay warm?’ ”

Marcus Aurelius, Meditations

Get up. Your purpose is not to be lazy and comfortable – it is to be useful to yourself and others.
