"Some things are in our control and others are not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, prope…"

"It is our attitude toward events, not events themselves, which determines how we will act."

"Fortify yourself with contentment, for this is an impregnable fortress."

"If you see anybody wail and complain, call him a slave, though he be clad in purple."

"Do not seek to have events happen as you want them to, but instead want them to happen as they do happen, and your life will go well."
