Taekwondo teaches children to pay attention and block out distractions. Pattern practice demands that children block out distractions and concentrate on making perfect motions. Sparring requires a student’s undivided attention at all times or they lose the match.
A disrespectful child gets no respect, so he or she turns that attitude inward and starts to see him or herself as a person who does not deserve respect. Taekwondo teaches children to be respectful at all times to everyone, and that they earn respect in the same measure that they give respect.
Taekwondo helps children become experts at something, which then gives them more self-confidence. Everybody knows that if you are good at something, you become confident in that thing, but that confidence also spills over into other areas of a child's life.
