From Meditations book 5 #6:

“Some People, when they do someone a favor, are always looking for a chance to call it in.  And some aren’t, but they’re still aware of it–still regard it as a debt.  But others don’t even do that. They’re like a vine that produces grapes without looking for anything in return.”

From: The Meditations, Book 5.

In he morning when thou risest unwillingly, let this thought be present-

I am rising to the work of a human being. Why then am I dissatisfied

if I am going to do the things for which I exist and for which I was
brought into the world? Or have I been made for this, to lie in the
bed-clothes and keep myself warm?-
