What would Marcus Aurelius say about procrastination?

You speak as though the work waits in some safe chamber until you feel noble enough to begin it. It does not wait. The hour passes into the keeping of death, and you are made smaller by each consent to delay. Ask yourself what part of the task is unbearable. Usually it is not the labor, but the thought of the labor. You suffer first in fancy, then again in idleness. Break that spell. Take up the nearest duty with an ordinary hand. Write the first line, clean the first corner, answer the first letter. A man is not restored by brooding over action, but by acting. Do not demand warmth from yourself before you move. Motion itself brings heat. The day asks only that you do what lies before you without complaint. What remains undone at night has judged your morning.

— Marcus Aurelius
