Lucy,
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. Never yield to force; never yield to the apparently overwhelming might of the enemy.
- Winston Churchill

And one of my favorites:
The truth is hate to those who hate the truth.
We shall fight on the beaches,we shall fight on the landing grounds, we shall fight in the fields and in the streets,we shall fight in the hills;but we shall never surrender.
