You can always win if you only enter competitions where winning is up to you. - Epictetus

God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.

These are not the circumstances that I want.’ Is it up to you to choose them? You have been given that particular body, these particular parents and brothers, this particular social position and place to live. You come to me hoping that I can somehow change these circumstances for you, not even conscious of the assets that are already yours that make it possible to cope with any situation you face.

Settle on the type of person you want to be and stick to it, whether alone or in company.
