Concentration is the ability to think about absolutely nothing when it is absolutely necessary.
Courage is resistance to fear, mastery of fear, not absence of fear. Except a creature be part coward, it is not a compliment to say it is brave.
Courage is the price that life exacts for granting peace.
George E. Woodberry
Defeat is not the worst of failures. Not to have tried is the true failure.
William Jennings Bryan
Destiny is not a matter of chance, it is a matter of choice; it is not a thing to be waited for, it is a thing to be achieved.
Discipline and concentration are a matter of being interested.
Alfred A. Montapert
Do not confuse motion and progress. A rocking horse keeps moving but does not make any progress.
Do not let what you cannot do interfere with what you can do.
Doctors and scientists said that breaking the four-minute mile was impossible, that one would die in the attempt. Thus, when I got up from the track after collapsing at the finish line, I figured I was dead.
Don't accept that others know you better than yourself. Work joyfully and peacefully, knowing that right thoughts and right efforts will inevitably bring about right results.
