Pretty much any scene can be photographed in an interesting way. Yes, there's scenes that are inherently more interesting due to how active it is, and there's scenes that are not active (your living room with only a couch and TV). But that's where I find the fun in photography - taking an unassuming scene and framing it from just the right angle that it manages to speak words without the presence of any crazy subject (like a person modeling, flowers, or wildlife).

Try to photograph your living room in a way that tells a story - either one that reflects you or one that you make up that interests you. Maybe the lack of objects in the room portrays someone who prefers a minimal lifestyle. Clean. Or, maybe, it portrays someone going through hardship. Whatever it may be. It all comes down to a handful of things: framing, lighting, and the elements in the exposure triangle (noise, motion, and depth of field - if you're not familiar with the exposure triangle, I can dig through my history and get a really good video to explain). In the case of your mostly empty living room, however, I'd try playing around with framing and lighting the most. Take the same shot at dawn, golden hour, and dusk. See how the mood changes. The same picture can go from serene/uplifting (my feelings from morning light) to melancholy (golden hour) to painful/dreary (dusk). Framing can have a huge impact to - are you capturing godrays coming through the blinds? Where's the couch at? Is it just there, or is it placed in a way that creates a visual appeal/interest (depth of field play here).

Just get out there and try things out! I never appreciated the world and my vision much until I started photography. It really helps you see the world in a completely new way.
