Structured content is a lot like a new closet. No amount of organization will work until you put everything in its rightful place.
This is a fantastic article that my new friend, Val Swisher, wrote about understanding structured content management. She is a marvelous speaker that I saw at Adobe Day at Lavacon, and spent some time with her afterwards. She's a creative and smart person! I love her analogy with the closet in this article! I definitely encourage you to read this article, because it's a great breakdown of how the whole concept works.
