Be Yourself is a Delphic maxim, Σαυτὸν ἴσθι, and may refer to:
"Today you are You, that is truer than true. There is no one alive who is youer than you."
"No need to hurry. No need to sparkle. No need to be anybody but oneself."
"No matter what you do, give it everything you have. Be the best, not the second best."
"Always be a first-rate version of yourself."
"Be as you wish to seem."
"Be yourself; no base imitator of another, but your best self."
"Why change? Everyone has his own style. When you have found it, you should stick to it."
"Courage is self-acceptance and self-love as you are."
"You have to believe in yourself."
"The world needs exactly who you are."
"Don't be afraid to be different."
"You are you. Now, isn't that pleasant?"
