“You will never have a greater or lesser dominion than that over yourself...the height of a man's success is gauged by his self-mastery; the depth of his failure by his self-abandonment. ...And this law is the expression of eternal justice. He who cannot establish dominion over himself will have no dominion over others.”
― Leonardo da Vinci

“And as a few strokes on the nose will make a puppy head shy, so a few rebuffs will make a boy shy all over. But whereas a puppy will cringe away or roll on its back, groveling, a little boy may cover his shyness with nonchalance, with bravado, or with secrecy. And once a boy has suffered rejection, he will find rejection even where it does not exist—or, worse, will draw it forth from people simply by expecting it.”
― John Steinbeck, East of Eden

“This is the other secret that real artists know and wannabe writers don’t. When we sit down each day and do our work, power concentrates around us. The Muse takes note of our dedication. She approves. We have earned favor in her sight. When we sit down and work, we become like a magnetized rod that attracts iron filings. Ideas come. Insights accrete.”
― Steven Pressfield, The War of Art

“Whether our action is wholesome or unwholesome depends on whether that action or deed arises from a disciplined or undisciplined state of mind. It is felt that a disciplined mind leads to happiness and an undisciplined mind leads to suffering, and in fact it is said that bringing about discipline within one's mind is the essence of the Buddha's teaching.”
― Dalai Lama XIV, The Art of Happiness
