“The first and best victory is to conquer self. To be conquered by self is, of all things, the most shameful and vile.”
― Plato

“One can't understand everything at once, we can't begin with perfection all at once! In order to reach perfection one must begin by being ignorant of a great deal. And if we understand things too quickly, perhaps we shan't understand them thoroughly.”
― Fyodor Dostoyevsky, The Idiot

“Anyone thinking of his own interests and seeking out friendship with this in view is making a great mistake. Things will end as they began; he has secured a friend who is going to come to his aid if captivity threatens: at the first clank of a chain that friend will disappear. These are what are commonly called fair-weather friendships. A person adopted as a friend for the sake of his usefulness will be cultivated only for so long as he is useful.”
― Seneca, Letters from a Stoic

“And those who were seen dancing were thought to be insane by those who could not hear the music.”
― Friedrich Nietzsche
