Never use Times New Roman as a display face (fail).

Never haphazardly capitalize Word For No Good Reason, even if they’re Not Proper Nouns.

I’ll tell you what … I’d take a book like this a lot more seriously if, in excusing mediocre designers from following guidelines that could seriously improve their work, it itself was well-designed.

But it’s not. And unless you’re certain you know what you’re doing, you could do far worse than following rules like these (although some of them, I think, were made up just for the sake of this book’s breaking them – several are things I’ve never even heard of, and are just plain silly).
