Relationships with other people and the world will usually be incomplete, partial, and sometimes frustrating.
So this creates a need for things like belief systems and personality, to fill in the gaps. Also, things like philosophies, possessions, money, art, music, fashion and personal style.
A danger is if these gap-fillers become mistaken for the whole of reality.
You can’t forget that huge parts of life are the unpredictable, incomplete and often chaotic relationships with other people and the world. And, that we need to embrace these parts of life too.
