Praxeology - Episode 3 - Purposeful Action

If you choose not to act, you still have made an action (/Hat Tip to Neil Peart).

Benjamin Franklin (1706 - 1790)

The best thing to give to your enemy is forgiveness; to an opponent, tolerance; to a friend, your heart; to your child, a good example; to a father, deference; to your mother, conduct that will make her proud of you; to yourself, respect; to all men, charity. Benjamin Franklin
