We must go on and on like the gun-horses, till we drop.

It is like going up a mountain. Each successive peak appears in turn the summit, and yet there is always another pinnacle beyond.

Success is stumbling from failure to failure with no loss of enthusiasm.

Persevere towards those objectives which are lighted for us by all the wisdom and inspiration of the past.

When you feel you cannot continue in your position for another minute, and all that is in human power has been done, that is the moment when the enemy is most exhausted, and when one step forward will give you the fruits of the struggle you have borne.

I can't change the direction of the wind, but I can adjust my sails to always reach my destination.
