If parents bring up a child with the aim of turning the child into a genius, they will cause a disaster. According to several leading educational psychologists, this is one of the biggest mistakes that ambitious parents make.
    Generally, the child will be only too aware of what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children. However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a sensible way, the child may succeed in doing very well — especially if the parents are very supportive of their child.
Michael Li is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him.
    Although Michael’s mother knows very little about music, Michael’s father plays the trumpet in a large orchestra. However, he never makes Michael enter music competitions if he is unwilling.
    Michael’s friend, Winston Chen, however, is not so lucky. Although both his parents are successful musicians, they set a too high standard for Winston.
    They want their son to be as successful as they are and so they enter him in every piano competition held. They are very unhappy when he does not win. "When I was your age, I used to win every competition I entered," Winston’s father tells him. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.
