Think like a photographer (or a guest who visits). Use the trick of snapping photos of your main spaces to see them on the screen. This will help you remove yourself from the rooms you see in person everyday. Consider even using photography to help you document sentimental clutter so you can free up some space in your home. Check out these tips on How A Camera Can Help Get Rid of Sentimental Clutter.
Consider what pieces of furniture you don't use in the space. And actually take them out if you're not ever going to use them. It sounds easy enough, but when you're a vintage furniture find addict, every piece has so much potential. Give the boot to pieces that you could use one day, and make more elbow room for the pieces you will use today.
Consider storing away some art and accessories. Refresh your space all year long by storing a quarter to half of your overflowing art and accessory collections away. It's a tough idea to swallow if you love absolutely everything you've collected, but it'll be easier for your beloved finds to stand out and shine when they have more of a starring role (instead of being half buried by other art!).
