Decorating a living room is beating me

Pick one thing to build from - a rug, a print, the sofa - and pull the colours from that. Most people stall because they're trying to choose everything at once. Sort the layout before buying anything: furniture pulled slightly off the walls and grouped round a conversation area, and a rug big enough that at least the front legs of the sofa and chairs sit on it. Lighting is the cheap win - two or three lamps instead of only the ceiling light changes how the whole room feels. Is it the layout or the style you're stuck on?
