I removed 2 pieces of furniture that weren't visually appealing or providing the functionality I needed, an awkward bookshelf and the card table I was using for art, and ordered replacements for both. Aesthetics are important in a space too, because if I hate to look at a piece of furniture, whether I'm aware of it or not, it creates negative feelings everytime I am in the room which blocks the positive energy.
Our home should be our sanctuary, a sacred place where we relax and rejuvenate. And if it's not providing that, then change is needed. I notice that I'm already feeling lighter when I walk in here. If you have a space in your home that's not working for you, take a step back and notice what it is that's not working. What do you need the space to provide? How do you want to use the space? How do you want to feel in the space? What small changes can you make to improve functionality, flow, or aesthetics?
