Pygmallion effect or reason for managing your expectations
According to Ovidius, Pygmallion was a Cypriot sculptor, who fell in love with an ivory woman statue he carved. The goddess Aphrodite appreciated his love and offerings and changed the statue to a real woman. Pygmallion then married her and they had a daughter. So much for the history or mythology, now let's go back to management. The phenomenon called Pygmalion effect says that others' expectations from a person are affecting that person's performance.
