"Wherever a process of life communicates an eagerness to him who lives it, there the life
becomes genuinely significant. Sometimes the eagerness is more knit up with the motor
activities, sometimes with the perceptions, sometimes with the imagination, sometimes with
reflective thought. But, wherever it is found, there is the zest, the tingle, the excitement of reality;
and there is 'importance' in the only real and positive sense in which importance ever anywhere
can be."
- William James, "On a Certain Blindness in Human Beings"
