Be Yourself is a Delphic maxim, Σαυτὸν ἴσθι, and may refer to:
"Make the most of yourself for that is all there is of you."
"Be yourself; no base imitator of another, but your best self."
"Courage is self-acceptance and self-love as you are."
"Learn to be okay with the fact that you're not for everyone. You are unique just the way you are."
"Be yourself, no matter what others think about you, you should hardly care about who pleased by you and who don't."
"The great honor in the world is to be what we pretend to be."
"The world needs exactly who you are."
"One comes to believe whatever one repeats to oneself sufficiently often, whether the statement be true of false. It comes to be the dominating thought in one's mind."
"Do you want to know who you are? Don't ask. Act! Action will delineate and define you."
"You have to believe in yourself."
"The greatest way to live with honour in this world is to be what we pretend to be."
"Never bribe yourself. Be whole. Be your own hero."
