As special as you are, you are no more special than anyone else
Utilitarianism
It is not ego-based however, personal good is not considered – it is the scope of the relevant consequences that determine the morality of the choice. Maximising overall “good/happiness” is the path to an ethical life for a Utilitarian.

Utilitarianism is an effort to provide an answer to the practical question “What ought a person to do?” The answer is that a person ought to act so as to maximize happiness or pleasure and to minimize unhappiness or pain.
