How long will you then still defer thinking yourself worthy of the best things, and in no matter transgressing the distinctive reason? Have you accepted the theorems (rules), which it was your duty to agree to, and have you agreed to them?
What teacher, then, do you still expect that you defer to him the correction of yourself? You are no longer a youth, but already a full-grown man. If then you are negligent and slothful, and are continually making procrastination after procrastination, and proposal (intention) after proposal, and fixing day after day, after which you will attend to yourself, you will not know that you are not making improvement, but you will continue ignorant (uninstructed) both while you live and till you die. Immediately, then, think it right to live as a full-grown man, and one who is making proficiency, and let everything which appears to you to be the best be to you a law which must not be transgressed. And if anything laborious, or pleasant or glorious or inglorious be presented to you, remember that now is the contest, now are the Olympic games, and they cannot be deferred; and that it depends on one defeat and one giving way that progress is either lost or maintained. Socrates in this way becomes perfect, in all things improving himself, attending to nothing except to reason. But you, though you are not yet a Socrates, ought to live as one who wishes to be a Socrates.
