Ultimate reality is a community of persons who know and love one another. That is what the universe, God, history, and life is all about. If you favour money, power, and accomplishment over human relationships, you will dash yourself on the rocks of reality. When Jesus said you must lose yourself in service to find yourself (Mark 8:35), he was recounting what the Father, Son and Holy Spirit have been doing throughout eternity.
You will, then, never get a sense of self by standing still, as it were, and making everything revolve around your needs and interests. Unless you are willing to to experience the loss of options and the individiual limitation that comes from being in committed relationships, you will remain out of touch with your own nature and the nature of things.
