Relationships are a predictor of the quality of life

Your social relationships are actually a strong predictor of the quality of life, both psychological and physical. Invest in your relationships; material possessions don't generally bring lasting happiness.

Your intimate and platonic relationships need to be nurtured with love and care in order for them to thrive and produce healthy relationship habits. With good social relations, we end up happier, less stressed, more resilient to pain, and lowered cognitive decline.
