At least that would be the definition in its fullest sense.
Of course everyone has a certain personality and, no matter in what degree, its possession is valuable.

Personality is an acorn, so to speak, which may be cultivated into a sturdy oak.

Personality is one's _inner self outwardly expressed_.

It represents the conquest of our weaknesses and naturally impresses our strength of character upon others.
With personality our foundation is firm.

On this pedestal we may stand squarely and face life with equanimity.
