Give your heart to the trade you have learnt, and draw refreshment from it. Let the rest of your days be spent as one who has whole-heartedly committed his all to the gods and is thenceforth no man's master or slave.
Marcus AureliusNature set a limit on sleep - as it did on eating and drinking. And youre over the limit. But not of working. There youre still below your quota. You dont love yourself enough. Or youd love your nature too and what it demands of you. People who love what they do wear themselves down doing it. They even forget to wash and eat.
Marcus Aurelius
