"I hate incompetence. I think it’s probably the only thing I do hate. But it didn’t make me want to rule people. Nor to teach them anything. It made me want to do my own work in my own way and let myself be torn to pieces if necessary." - Howard Roark, The Fountainhead.
"No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable." - Socrates.
“Our duties naturally emerge from such fundamental relations as our families, neighborhoods, workplaces, our state or nation. Make it your regular habit to consider your roles-parent, child, neighbor, citizen, leader-and the natural duties that arise from them. Once you know who you are and to whom you are linked, you will know what to do.” - Epictetus
"No tree becomes rooted and sturdy unless many a wind assails it. For by its very tossing, it tightens its grip and plants its roots more securely; the fragile trees are those that have grown in a sunny valley." - Seneca
"Do you suppose that you alone had this experience? Are you surprised, as if it were a novelty, that after such a long travel and so many changes of scene, you have not been able to shake off the gloom and heaviness of your mind? You need a change of soul rather than a change of climate. Though you may cross vast spaces of sea , and tough our Vergil remarks, Lands and cities are left astern, your faults will follow you wherever you travel." - Seneca to Lucilius, Moral Letters.
