With their rich imagination, they will come up with fantastic dreams. There are a lot of examples in history. Many great men were dreamers when they were children. One such dreamer was Thomas Edison. He was in school for only three months because the teacher thought he was kind of stupid and didn't want to teach him. But his achievements were greater than everyone else's in his time. He made 1, 093 inventions during his lifetime.
