Letters from a Stoic 96 : 1

Spite of all do you still chafe and complain, not understanding that, in all the evils to which you refer, there is really only one – the fact that you do chafe and complain? If you ask me, I think that for a man there is no misery unless there be something in the universe which he thinks miserable. I shall not endure myself on that day when I find anything unendurable. I am ill; but that is a part of my lot. My slaves have fallen sick, my income has gone off, my house is rickety, I have been assailed by losses, accidents, toil, and fear; this is a common thing. Nay, that was an understatement; it was an inevitable thing.
