Then never, never, never give up. Persistence is to the character of man as carbon is to steel. Why man, I have gotten a lot of results. I know of several thousand things that won't work. Persistence and determination alone are omnipotent.
Most people give up just when they're about to achieve success.
They quit on the one yard line. They give up at the last minute of the game, one foot from a winning touchdown. We can do anything we want to do if we stick to it long enough. Don't worry about being clever. Trust to hard work, perseverance and determination.
