General Douglas MacArthur
What this power is, I cannot say. All I know is that it exists and it becomes available only when you are in that state of mind in which you know exactly what you want and are fully determined not to quit until you get it.
Perseverance is a great element of success. If you only knock long enough
at the gate, you are sure to wake up somebody .
Fight one more round.
When your arms are so tired that you can hardly lift your hands to come on guard,
fight one more round.
When your nose is bleeding and your eyes are black and you are so tired that you wish your opponent would crack you one on the jaw and put you to sleep,
fight one more round,
remembering that the man who always fights one more round is never whipped.
