A quitter never wins—and—a winner never quits.
Be persistent no matter how slowly you may, at first, have to move. With persistence will come success.
Before success comes in any man's life, he is sure to meet with 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.
If one does not possess persistence, one does not achieve noteworthy success in any calling.
In trying times, don't stop trying.
It is always better to fail in doing something than to excel at doing nothing.
Never be discouraged when you make progress, no matter how slow or small. Only be wary of standing still.
Never give up on what you really know you should do. Failure is waiting on the path of the least persistence.
Nobody and nothing can keep you down unless you decide not to rise again.
Obstacles can temporarily detour you, but only you can make you stop.
One person with commitment, persistence, and endurance will accomplish more than a thousand people with interest alone.
