How loved ones see you affects how you see yourself. When people see you in a positive or negative light, they treat you accordingly – and this influences your self-perceptions. In 1999, a group of researchers found that people become more like their ideal selves when they have a partner who sees them as they’d like to be. This “Michelangelo effect” was named after the legendary artist who created stone sculptures based on the images he saw in the raw material, just as partners help to shape their companion into the ideal self that they carry within. Of course, when partners or close friends see you in a less favorable light, that perception will affect you negatively. So, keep this in mind as you choose your partner and friends.
