There exists within you an "economy of selves." However, let’s call it a community or a troupe, where each personality (or partition) with its concomitant desires proclaims its importance to running the whole self.
In such a case, to remain entire the whole must sacrifice to save the fragment.

Some parts of you must do things harmful to other parts, essentially triaging desires. The whole will always be sick (divided against itself) because of this.

The difficulty of a singular self (or universality) to emerge, or to transcend to an ideal state, is the need to either rid or harmonize discord. Optimizing the self is radically tyrannical to the self.
