When something happens, the only thing in your power is your attitude toward it. It is not the things that disturb us, but our interpretation of their significance. Things and people are not what we wish them to be nor are they what they seem to be. They are what they are.
EpictetusFreedom is the only worthy goal in life. It is won by disregarding things that lie beyond our control. Stop aspiring to be anyone other than your own best self: for that does fall within your control.
EpictetusIf you want to improve, be content to be thought foolish and stupid with regard to external things. Don't wish to be thought to know anything; and even if you appear to be somebody important to others, distrust yourself. For, it is difficult to both keep your faculty of choice in a state conformable to nature, and at the same time acquire external things. But while you are careful about the one, you must of necessity neglect the other
EpictetusNothing outside the will can hinder or harm the will; it can only harm itself. If then we accept this, and, when things go amiss, are inclined to blame ourselves, remembering that judgment alone can disturb our peace and constancy, I swear to you by all the gods that we have made progress.
Epictetus
