Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.
EpictetusBid a singer in a chorus, Know Thyself; and will he not turn for the knowledge to the others, his fellows in the chorus, and to his harmony with them?
EpictetusTo Epictetus, all external events are determined by fate, and are thus beyond our control, but we can accept whatever happens calmly and dispassionately. Individuals, however, are responsible for their own actions which they can examine and control through rigorous self-discipline. Suffering arises from trying to control what is uncontrollable, or from neglecting what is within our power. As part of the universal city that is the universe, human beings have a duty of care to all fellow humans. The person who followed these precepts would achieve happiness.
