Epictetus
What concerns me is not the way things are, but rather the way people think things are.
Fortify yourself with contentment, for this is an impregnable fortress.
No man is free who is not master of himself.
Only the educated are free.
First say to yourself what you would be , and then do what you have to do.
There is only one way to happiness, and that is to cease worrying things which are beyond the power of our will.
