The Artist Studios

What types of things do you see in more that one artist's space?
In most of the artist spaces i can see that you can deffinatley see what kind of art they do or their personality they have through their space. One of the artist had paintings everywhere with paint on the floor wallls and ceiling and pieces of art all over the place and you can see they are a sporadic person that is messy and is wild. and then their was anpther artist that had everything organized and orderly and nothing on the floor and all white wallls and no clutter or any space.
Why do you think these things appear in so many different artists' studios?
I feel that ones space is a reflection on their personality and how they work and that it is an easy way to see what kind of style they are
