What we live by we die by.

When my heart can beat no more, I hope I die for a principle or a belief that I have lived for.

No one really knows why they are alive until they know what they'd die for.

I have an irrepressible desire to live till I can be assured that the world is a little better for my having lived in it.

Just as in ordinary life a man with a fixed life-goal... will always be superior to others who live aimlessly.

The life of a nation is the fullness of the measure of its will to live.
