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.

Consider the postage stamp, my son. It secures success through its ability to stick to one thing till it gets there.

If you can force your heart and nerve and sinew to serve your turn long after they have gone, and so hold on when there is nothing in you. Except the Will which says to them; ''Hold on!''

To persevere, trusting in what hopes he has, is courage in a man.

Perseverance, self-reliance, energetic effort, are doubly strengthened when your rise to battle again.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

Austere perseverance, hash and continuous... rarely fails of its purpose, for its silent power grows irresistible greater with time.

Endurance is the crowning quality...

If you only knock long enough and loud enough at the gate, you are sure to wake up somebody.

Never give in! Never give in! Never, never, never, never -- in nothing great or small, large or petty. Never give in except to convictions of honor and good sense.
