"I believe that each young person is different from any other who has ever lived, as different as his fingerprints: that he could bring to the world a wonderful and special way of solving unsolved problems, that in his special way, he can be great. Now don't misunderstand me. I recognize that this merely great person, as distinguished from the genius, will not be able to bridge from field to field. He will not have the ideas that shorten the solution of problems by hundreds of years. He will not suddenly say that mass is energy, that is genius. But within his own field he will make things grow and flourish; he will grow happy helping other people in his field, and to that field he will add things that would not have been added, had he not come along."
