The baby looks at things all day without winking; that is because his eyes are not focused on any particular object. He goes without knowing where he is going, and stops without knowing what he is doing. He merges himself within the surroundings and moves along with it. These are the principles of mental hygiene.

I cannot tell if what the world considers ‘happiness’ is happiness or not. All I know is that when I consider the way they go about attaining it, I see them carried away headlong, grim and obsessed, in the general onrush of the human herd, unable to stop themselves or to change their direction. All the while they claim to be just on the point of attaining happiness.
