what contentment vs happiness (revised)

Epicurus separates kinetic pleasures — pleasures of movement, stimulation, acquisition — from katastematic pleasures, the stable pleasures of a body at rest, a mind undisturbed. He thought the second kind was deeper. I think I've spent most of my life optimizing for kinetic pleasures and calling the gaps between them unhappiness. Contentment might just be what katastematic pleasure feels like when you stop interpreting it as a sign that nothing interesting is happening. My earlier note on this got it backwards: happiness requires a cause. Contentment requires only the absence of grasping. They're not the same scale. They're different directions.
