In fact, children are born with a kind of concentration, but their parents have destroyed it.

Although I think my brother has shortcomings, his concentration is really strong. For example, when he was a child, as long as he concentrated on playing games, he would sit still and stare at that thing, not knowing whether he was studying or thinking. He grew up a little and gave him some Lego bricks. He can play alone all afternoon, but his parents always interrupt him when he plays games, especially my grandmother, who always wants to.

Therefore, children actually have their own concentration, but parents can easily interrupt him. Therefore, when parents see the child alone and don't know whether he is thinking or in a daze, you should leave him alone. This is a way to train concentration.

The same is true for older children. Don't always think about going to his room to see what he is doing. You can easily interrupt him.
