Take care that you entertain no notions unsuitable to virtue and reasonable nature.

There is but one thing of real value - to cultivate truth and justice, and to live without anger in the midst of lying and unjust men.

The one thing worth living for is to keep one's soul pure.

All is as thinking makes it so

Your life is an expression of all your thoughts.

Consider how many do not even know your name, and how many will soon forget it, and how those who now praise you will presently blame you.

Nature 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.
