I'm pretty minimalist. There aren't large numbers of ornaments, knick-knacks and curios in the house. I find cleaning very therapeutic, the process of rejuvenating something and getting it back to its best. I could easily be a professional cleaner and have often thought of doing it as a job!
This pretty much described me, no pictures, no knick-knacks, usually a desk and bed, maybe a table, chairs and a sofa (and kitchen stuff, all neatly put away. I have always lived a rather Spartan existence (though have never kicked a Persian messenger down a well). I consider myself to be rather neat and keep a pretty clean, tidy dwelling. Like some of the INFJ descriptions, I do, however usually have one cluttered closet full of accumulated junk that I do not use but for some reason have likewise not discarded or sorted. Clutter drives me absolutely insane, even the thought of the stuff in the closet which I cannot even see. I recently solved the closet issue by giving away everything I own, save for my backpack and some clothes. I do not foresee myself purchasing anything in the near (and far) future that will not fit in my backpack. The place I live in now has no closet space, and the owner left some things there that I do not need, so these items are piled into a pile in the corner of one of the two rooms.
The military further reinforced my cleanliness with six weeks of basic training, followed by a year and a half long tech school. I also find cleaning rather therapeutic and have likewise considered cleaning professionally, and several jobs I have held involved such work. That said, I do not clean the entire mud hut everyday, but there are rarely dirty dishes in the sink and the floor is generally swept.
All that said, I have nothing on my ISFJ aunt (tested, confirmed). Her house gleams, and is full of antiques and nice things. I am generally afraid to sit on anything at her house.
