I really don't like clutter, so it's an engrained habit of mine to just always keep things un-cluttered. So, my place always looks 'clean'.
But when it comes to actual cleaning, it's a chore that I have to force myself to do. The bathroom doesn't get cleaned that often (maybe every 3-4 weeks), I vacuum maybe once a week, I do the dishes maybe once a week - however, I don't have food-caked dishes sitting around my kitchen... I rinse things off, then let these dishes pile up in one half of my sink and then clean all of it in one shebang, maybe once a week). Countertops, stove, etc, I always keep wiped down.
Also, I live alone... so because I live pretty 'cleanly', I don't feel like I really have to Officially Clean that often.
"...On and on and on and on he strode, far out over the sands, singing wildly to the sea, crying to greet the advent of the life that had cried to him." - James Joyce
I organize the shit out of everything because it tends to save me time and headache later on. Or, well, I organize to the extent that it minimizes headache--sorting clothes by color, for example, doesn't do a damn thing.
I'm not so conscientious about cleaning per se, but in the process of organizing certain stuff, it gets cleaned anyway--dirty dishes belong in the dishwasher, for example.
Fortunately, I have tile floors, minimal needs, and a small, manageable yard--so cleaning on its own is pretty flippin' easy.
