Depends on what you mean.

My space is clean, but not that tidy. My desk has a lot of stuff on it. But I mean... my clothes are organised by type (as in what kind of top, pants or skirt) and colour. My books used to be organised by author's name alphabetically. My dvds and game discs used to be organised by title. I just finished cleaning out my closet earlier. Think I'll get to the books soon.
