Strength does not come from physical capacity. It comes from an indomitable will.

God cannot at the same time impose his will upon his children and also maintain his purpose for man.

Be strong! Don't talk of ghosts and devils.

If you are pure, if you are strong, you, one man are equal to the whole world.

The world is the great gymnasium where we come to make ourselves strong.

The cheerful mind perseveres and the strong mind hews its way through a thousand difficulties.
