Well, I dont have a photo setup in a cubed size room. I'm going up north in a week and I have some ideas of photos to do so I'll report back with those but where I am now, not much I can do here.
Sounds as though you're lacking not only in photographic skills but creativity as well..... surely you can find SOMETHING to shoot where you are right now! Just look around you: potential photographs are everywhere.
As for having "a photo setup in a cubed size room...." sometimes that's not necessary at all to get an interesting or artistic shot. Although I do have a light tent and various lights, there have been times when I've gotten some pretty cool images by setting things up on my kitchen counter, allowing natural light to come in through the adjacent windows..... Playing with the light, that's key. This is the kind of thing you need to learn and the best way of doing that is simply to do it -- experiment! An advantage of using digital cameras is the immediate feedback and also the absence of concern about the inherent limitations of a 24 or 36 exposure roll of film. With digital memory we have so much more space in which to experiment.
Grab that camera and get out there and really LOOK at the world around you.....
Here's an example of something I shot one day while experimenting:
The setup? On the kitchen countertop, a piece of shiny (reflective) black plastic , natural lighting from my kitchen windows.... and the camera. Oh, yes, the camera.....my iPhone.
Sure, this probably wouldn't win any awards if blown up into an 11 x 14, but on the other hand, I think it's still a rather interesting image.....
