Too many people think graphic design is not a specialty, but something anyone can do, because the tools to make decent-looking Web pages, newsletters, books, and the like are readily available. But design isn't putting stuff on a page. It's about solving visual problems through an iterative process of decisionmaking, which may involve consultation, or may happen in private. If you can't master that process, you can't work in the field.
