There's probably also a lot of useful advice that our minds filter out because it scans as obvious or trivial. Even when I'm trying to give maximally effective advice, I usually spend a lot of effort optimizing it for style; the better something sounds, the more people dwell on its implications and the likelier it is to stick. Fortunately, most messages leave plenty of latitude for presentation.

Alternately, you could try dressing simple advice up in enough cultural tinsel that it looks profound, as suggested here.
