“How long are you going to wait before you demand the best for yourself and in no instance bypass the discriminations of reason? You have been given the principles that you ought to endorse, and you have endorsed them. What kind of teacher, then, are you still waiting for in order to refer your self-improvement to him? You are no longer a boy, but a full-grown man. If you are careless and lazy now and keep putting things off and always deferring the day after which you will attend to yourself, you will not notice that you are making no progress, but you will live and die as someone quite ordinary.
From now on, then, resolve to live as a grown-up who is making progress, and make whatever you think best a law that you never set aside. And whenever you encounter anything that is difficult or pleasurable, or highly or lowly regarded, remember that the contest is now: you are at the Olympic Games, you cannot wait any longer, and that your progress is wrecked or preserved by a single day and a single event. That is how Socrates fulfilled himself by attending to nothing except reason in everything he encountered. And you, although you are not yet a Socrates, should live as someone who at least wants to be a Socrates.”
― Epictetus (From Manual 51)

“Non est ad astra mollis e terris via" - "There is no easy way from the earth to the stars”
― Seneca

“Be careful when you cast out your demons that you don’t throw away the best of yourself.”
― Friedrich Nietzsche

“Lightly, caressingly, Marie Antoinette picked up the crown as a gift. She was still too young to know that life never gives anything for nothing, and that a price is always exacted for what fate bestows. She did not think she would have to pay a price. She simply accepted the rights of her royal position and performed no duties in exchange. She wanted to combine two things which are, in actual human experience, incompatible; she wanted to reign and at the same time to enjoy.”
― Stefan Zweig, Marie Antoinette: The Portrait of an Average Woman
