Some things are up to us [eph' hêmin] and some things are not up to us. Our opinions are up to us, and our impulses, desires, aversions–in short, whatever is our own doing. Our bodies are not up to us, nor are our possessions, our reputations, or our public offices, or, that is, whatever is not our own doing.

From now on practice saying to everything that appears unpleasant: You are merely an appearance and NOT what you appear to be.

When any person treats you ill or speaks ill of you, remember that he does this or says this because he thinks it is his duty. It is not possible, then, for him to follow that which seems right to you, but that which seems right to himself.

Within our control are our own opinions, aspirations, and desires and the demons that distract us from these goals. Outside of our control are such things as what kind of body we have, whether or not we are born into wealth, and how we are regarded by others.

Not every difficult and dangerous thing is suitable for training, but only that which is conducive to success in achieving the object of our effort.

When you are offended at any man's fault, turn to yourself and study your own failings. Then you will forget your anger.

You can be invincible, if you enter into no contest in which it is not in your power to conquer.
