Social comparison theory states that we determine our own social and personal worth based on how we stack up against others we perceive as somehow faring better or worse. We sometimes compare ourselves to others as a way of fostering self-improvement, self-motivation, and a positive self-image.
Human beings are social animals, and the tenor of our social life is one of the most important influences on our mental and physical health. Without positive, durable relationships, both our minds and our bodies fall apart.
