Enchiridion 51

“How long are you going to delay to deem yourself worthy of the best things, and in nothing to transgress against the distinctive reason? You are no longer a youth, but already a full-grown man. If you are now negligent and slothful, and are always making delay after delay, and fixing one day after another, after which you will attend to yourself, you will forget your progress, and you will continue to be an ordinary person, living and dying.”
