The inability to do work...

Entropy may be thought of as a way to quantify the inability to get things done. The greater the entropy of a system, the less work it can accomplish. A collection of objects at rest relative to each other, with no forces acting between them and at the same temperature as their surroundings could not have much impact on their universe. That would be a high entropy system.

Entropy and energy are in a sense inverses of each other. High entropy systems are characterized by uniformity. If nothing distinguishes one location in space from another, there is no motivation for objects to change positions or otherwise get involved in the goings on of their universe. High energy systems are characterized by distinction. High is different than low, fast is different than slow and hot is different than cold.
