Sloth makes all things difficult, but industry, all things easy. He that rises late must trot all day, and shall scarce overtake his business at night, while laziness travels so slowly that poverty soon overtakes him.
Before success in any man's life he is sure to meet with much temporary defeat and, perhaps, some failure. When defeat overtakes a man, the easiest and most logical thing to do is to quit. That is exactly what the majority of men do.
