Intelligence doesn't equal happiness.

You want a TV example of that, there's an episode of House, MD where a super-genius dumbs himself down because he's happier when he's like the people around him and not constantly being aware of how much stupider they are.

But if intelligence equals happiness, really smart people wouldn't be depressed and commit suicide.

If Charlie were happy, but dumb, I would take that as a win. Because he's going to live the rest of his life happy.

Don't remember it.
