"What the mind of man can conceive and believe, it can achieve."
"Before success comes in any man's life he is sure to meet with much temporary defeat and, perhaps, some failures. 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."
"No man is ever whipped, until he quits -- in his own mind."
"Persistence is to the character of man as carbon is to steel."
"The majority of men meet with failure because of their lack of persistence in creating new plans to take the place of those which fail."
"Victory is always possible for the person who refuses to stop fighting."
"What we do not see, what most of us never suspect of existing, is the silent but irresistible power which comes to the rescue of those who fight on in the face of discouragement."
