“This is wholly up to you—who is there to prevent you being good and sincere?” Marcus Aurelius often reminded himself of the power he was granted by nature—the power to choose his actions and craft his own character. He said people can’t admire you for what’s been granted to you by nature, but there are many other qualities to cultivate. “So display those virtues which are wholly in your own power—integrity, dignity, hard work, self-denial, contentment, frugality, kindness, independence, simplicity, discretion, magnanimity.”
