Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no help at all."
"Never give in! Never give in! Never, never, never. Never -- in anything great or small, large or petty -- never give in except to convictions of honor and good sense."
Studies indicate that the one quality all successful people have is persistence. They're willing to spend more time accomplishing a task and to persevere in the face of many difficult odds. There's a very positive relationship between people's ability to accomplish any task and the time they're willing to spend on it."
