"You have to take an active role in making yourself happy. That's why I say happiness is a choice. Because you have to choose it."

In war, in some sense, lies the very genius of law. It is law creative and active; it is the first principle of the law. What is human warfare but just this, - an effort to make the laws of God and nature take sides with one party. Men make an arbitrary code, and, because it is not right, they try to make it prevail by might. The moral law does not want any champion. Its asserters do not go to war. It was never infringed with impunity. It is inconsistent to decry war and maintain law, for if there were no need of war there would be no need of law.

— Henry David Thoreau
