Seek Not the Good in External Things – Epictetus

"If 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" Epiktet

"As long as anyone believes that his ideal and purpose is outside him, that it is above the clouds, in the past or in the future, he will go outside himself and seek fulfillment where it cannot be found. He will look for solutions and answers at every point except where they can be found- in himself." Erich Fromm
