Two quotes: How the devil is dressed, and escaping from prison

I came across two quotes recently that seem related ... and not necessarily just in a spiritual/religious way:

“The devil doesn’t come dressed in a red cape and pointy horns. He comes as everything you’ve ever wished for.”

AND:

“The best way to keep a prisoner from escaping is to make sure he never knows he’s in prison.”

Lately I’ve been thinking about how some people get to a certain point and then never mature any more. It’s like maybe they get everything they ever wanted, and they stop there. They become comfortable or complacent, and in doing so, they create their own prison.
