“Do not afflict others with anything that you yourself would not wish to suffer. if you would not like to be a slave, make sure no one is your slave. If you have slaves, you yourself are the greatest slave, for just as freedom is incompatible with slavery, so goodness is incompatible with hypocrisy.”
― Epictetus

“If someone speaks badly of you, do not defend yourself against the accusations, but reply; "you obviously don't know about my other vices, otherwise you would have mentioned these as well”
― Epictetus

“Of all things, I liked books best.”
― Nikola Tesla

“Most of what passes for legitimate entertainment is inferior or foolish and only caters to or exploits people's weaknesses. Avoid being one of the mob who indulges in such pastimes. Your life is too short and you have important things to do. Be discriminating about what images and ideas you permit into your mind. If you yourself don't choose what thoughts and images you expose yourself to, someone else will, and their motives may not be the highest. It is the easiest thing in the world to slide imperceptibly into vulgarity. But there's no need for that to happen if you determine not to waste your time and attention on mindless pap.”
― Epictetus, The Art of Living: The Classical Manual on Virtue, Happiness and Effectiveness
