Sometimes genius is slow coming to the surface. Think your youngster is a slow learner? It's possible he's just not interested in the trivial. The fact is that many of our most famous people showed no indications of being outstanding when they were young. To the contrary, many of them, like Thomas Edison, were actually considered slightly slower than their contemporaries. Two of the world's best loved humorists, Will Rogers and Mark Twain, showed little interest either in school or in humor in their early years. As a child, Albert Einstein was slow in learning to talk; then as a boy he was considered backward. Ignace Paderewski, the great Polish pianist, was in his late teen years before he showed any interest in learning to play the piano.
