Take an inventor. No man ever invents anything unless he insists day after day, in spite of discouragements, in spite of failures, in spite of opposition, sometimes in spite of the stealings of people who would rob him of what he has already accomplished. The man who has the real desire to be an inventor keeps on and on, compelling his will to rewill what he has already willed, and I could fill these pages with the life stories of men who have determined, and of women who have determined, and who have achieved because they have learned this lesson of the insistence of the will. I once had the pleasure of talking with Thomas A. Edison, in his laboratory, in Orange, N. J. I said, pointing to a mass of interesting looking materials: "What is this, Mr. Edison?" He said, "Oh, I have been working for thirty years on that thing." "How are you getting along with it?" He replied, "Well, sometimes I think we are making progress, and then again I think we are not, but the only way we can achieve is by keeping everlastingly at it, and when I can't work, I set my men to work on it, and we are slowly getting results." And so Mr. Edison every once in awhile astounds the world with some marvelous achievement. People suppose he stumbles on it--that he discovers it in a moment, and perhaps he does, but that moment was made possible by the thousands upon thousands of moments that were as steps he had taken leading up to the place where the vision burst upon him. Do you see the thought? It is the Insistence of the Human Will that compels achievement. It is the man that never lets up that gains the reward. Fifty years ago a man named Judah set out to survey a railroad across the great Sierra Nevada range of mountains, that vast barrier that seems to separate California from the rest of the world. The people practically said, "You are a fool to think of such a thing," but he calmly replied: "I know I can put a road through; I am going to try it anyhow." So he began to climb those mountain heights. He threaded the passes one by one. He took his men and they worked day after day, week after week, month after month, upon what seemed to be an impossibility. What was the result? He kept at it until he achieved. He made his plans and made them so well that he ultimately succeeded in convincing the House of Representatives and the United States Senate that such a railroad was possible.
