You do, and yours is unique. No one else on earth has your particular assemblage of spontaneity, modesty, humor, or insightfulness. To say someone has personality doesn't just mean someone is outrageous or flamboyant, such as former Italian Prime Minister Silvio Berlusconi or the late pianist Liberace. Even the most retiring of wallflowers has personality — albeit a shy and quiet one. The word personality comes from persona, Latin for “mask.”

That's telling, isn't it?

Screen legend Mae West likened personality to “glitter,” and while she could boast of many assets, she declared that personality was the most important factor in the success of any actress. Psychologist Erich Fromm considered personality to be “the most important product” of man's effort — the fulfillment of his potential. Albert Camus thought one's personality continued to grow and change. In the absurdist philosopher's typically upbeat fashion he wrote, “We continue to shape our personality all our life. If we knew ourselves perfectly, we should die.”

Personality pertains to human differences, but it also has a lot to do with human similarities. Few people are one clear-cut personality type, such as cheerful. It's far more likely that you fall somewhere on a continuum between cheerful and dour most of the time.
