There is no one great man. Only millions of men and women in possession of tiny pieces of greatness, which when put together, when assembled in the aggregate make the whole. I am a piece of a very large jigsaw puzzle. One of the corner pieces. The one you go for first - important for a time, different from most of the others. But then, in the end, in the big picture, just one of many.
