If the mind is to emerge unscathed from this relentless struggle with the unforeseen, two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to the truth; and second, the courage to follow this light wherever it may lead.

It is even better to act quickly and err than to hesitate until the time of action is past.

Pursue one great decisive aim with force and determination.

Courage, above all things, is the first quality of a warrior.

If the leader is filled with high ambition and if he pursues his aims with audacity and strength of will, he will reach them in spite of all obstacles.

Although our intellect always longs for clarity and certainty, our nature often finds uncertainty fascinating.

Never forget that no military leader has ever become great without audacity.

The backbone of surprise is fusing speed with secrecy.
