When your child is in an athletic environment that boosts hi self-esteem, she will learn faster, enjoy herself more and perform better under competitive pressure. This s how self-esteem gets established. When your interactions with your child make her feel good about herself, she will, in turn, learn to treat herself this very same way. This does NOT mean that you have to incongruently compliment your child for a great effort after they have just performed miserably. In this situation being empathic and sensitive to her feeling is what is called for.
Self esteem makes the world go around.
Make your child feel good about herself and you've given her a gift that lasts a lifetime. DO NOT interact with your child in a way that assaults her self-esteem by degrading, embarrassing or humiliating her. The most successful people in and out of sports do two things different than everyone else. Fear of failure or humiliation causes one to be tentative and non-active. In fact, most performance blocks and poor performances are a direct result of the athlete being preoccupied with failing or messing up.
