Quotes: Miles to Go Before I Sleep

When the battle is over, your work is not done. Your duty is not a destination. It is a journey. Victory is merely a landmark on that road, you will never reach a point where your work is done and you can leave the fighting to others. You will die with the road still to be walked.
Daenyathos - "The Bullet and the Skull", Warhammer 40,000

"I am tired, weary, and I haven't a hope left. But I have to go on trying to get to the mountain, as long as I can move."
Frodo Baggins, The Lord of the Rings
