Yup. I am whole in of myself. I don't need anyone to "complete" me.
But the company we choose to keep? It matters, since the company we keep affects us. That companionship from those people is either bringing us toward our best selves or NOT bringing us toward our best selves.
That's why parents worry about the kids their children pal around with. As adults -- it STILL matters. Who we pal around and keep company with.
Behooves us to choose wisely.
