“The purpose of morality is to teach you, not to suffer and die, but to enjoy yourself and live.” — Galt’s Speech, in Ayn Rand’s Atlas Shrugged
Morality is a code of values that an individual must choose to follow to live one’s life in reality. 
Morality is a set of universal, rationally discovered and objectively validated principles that one must apply to the particular concretes of one’s everyday life if one wishes to continue living in reality.
