Just as with traditional journal or diary-keeping, where one may pen musings about life, documentation of experiences, struggles, daily notes, letters, random thoughts or whatever's on your mind, an art journal can combine these written elements (or with little or no writing) along with unstructured and personal art.
The art journal can be about anything that you like.
