I never did anything worth doing by accident, nor did any of my inventions come indirectly through accident, except the phonograph. No, when I have, fully decided that a result is worth getting, I go about it, and make trial after trial, until it comes.
Genius is one percent inspiration, ninety-nine percent perspiration.
Opportunity is missed by most people because it is dressed in overalls and looks like work.
Sure I am of this, that you have only to endure to conquer. You have only to persevere to save yourselves, and to save all those who rely upon you. You have only to go right on, and at the end of the road, be it short or long, victory and honor will be found.
He who endures, conquers.
Obstacles cannot crush me. Every obstacle yields to stern resolve. He who is fixed to a star does not change his mind.
