I have heard some children complained that they were happier at school than at home. They said, they really wanted to make more effort to become a better self in order to get praise from teacher at school. Whether teachers or classmaters all encouraged them to make progress.But when they went home, their parents assumed that they still had a lot of knowledges to learn and doing homework was the only choise.In fact, they really wanted to share the interesting things happed at school with their parents, and then did homework without their parents' requests. But after losing parents' trust, they suddenly lost interest on they studying. From above examples, I clearly realize that how to became a self-desciplined child mainly depends on how much they accept themsleves and believe they are the best. we can simply call it confidence. But buiding confidence is affected by both their teachers and parents.In the process,parents always make mistakes.
