PS

I can see how one can say that you are as important a part of the world as anybody else, so the value/benefit you create for yourself is your contribution to the common good, but it sort of gets circular; so, while acknowledging that self-love, self-respect, self-esteem, self-pleasuring, self-development are all GREAT things, I will take the standard approach that holds that people are (primarily) judged by the value they create for others, not themselves.
