“It is the power of the mind to be unconquerable.”
― Seneca, The Stoic Philosophy of Seneca: Essays and Letters

“You know yourself what you are worth in your own eyes; and at what price you will sell yourself. For men sell themselves at various prices. This is why, when Florus was deliberating whether he should appear at Nero's shows, taking part in the performance himself, Agrippinus replied, 'Appear by all means.' And when Florus inquired, 'But why do not you appear?' he answered, 'Because I do not even consider the question.' For the man who has once stooped to consider such questions, and to reckon up the value of external things, is not far from forgetting what manner of man he is.”

“There is nothing worse than a sharp image of a fuzzy concept.”
― Ansel Adams

“For what prevents us from saying that the happy life is to have a mind that is free, lofty, fearless and steadfast - a mind that is placed beyond the reach of fear, beyond the reach of desire, that counts virtue the only good, baseness the only evil, and all else but a worthless mass of things, which come and go without increasing or diminishing the highest good, and neither subtract any part from the happy life nor add any part to it?
A man thus grounded must, whether he wills or not, necessarily be attended by constant cheerfulness and a joy that is deep and issues from deep within, since he finds delight in his own resources, and desires no joys greater than his inner joys.”
― Lucius Annaeus Seneca, The Stoic Philosophy of Seneca: Essays and Letters
