Feminism is an endeavor to change something very old, widespread, and deeply rooted in many, perhaps most, cultures around the world, innumerable institutions, and most households on Earth—and in our minds, where it all begins and ends.

A woman goes walking down a thousand-mile road. Twenty minutes after she steps forth, they proclaim that she still has nine hundred ninety-nine miles to go and will never get anywhere.
