The Enchiridion (c. 135)
Context: Never call yourself a philosopher, nor talk a great deal among the unlearned about theorems, but act conformably to them. Thus, at an entertainment, don't talk how persons ought to eat, but eat as you ought. For remember that in this manner Socrates also universally avoided all ostentation. And when persons came to him and desired to be recommended by him to philosophers, he took and recommended them, so well did he bear being overlooked. So that if ever any talk should happen among the unlearned concerning philosophic theorems, be you, for the most part, silent. For there is great danger in immediately throwing out what you have not digested. And, if anyone tells you that you know nothing, and you are not nettled at it, then you may be sure that you have begun your business. For sheep don't throw up the grass to show the shepherds how much they have eaten; but, inwardly digesting their food, they outwardly produce wool and milk. Thus, therefore, do you likewise not show theorems to the unlearned, but the actions produced by them after they have been digested. (46).

Ich soll niemals anders verfahren als so, dass ich auch wollen könne, meine Maxime solle ein allgemeines Gesetz werden.
Kant's supreme moral principle or "categorical imperative"; Variant translations:
Act only on that maxim which you can at the same time will that it should become a universal law.
Act as if the maxim of thy action were to become by thy will a universal law of nature.
So act that your principle of action might safely be made a law for the whole world.
May you live your life as if the maxim of your actions were to become universal law.
Live your life as though your every act were to become a universal law.
Do not feel forced to act, as you're only willing to act according to your own universal laws. And that's good. For only willfull acts are universal. And that's your maxim.
