Look around: What do you see? If it's anything like our surroundings, there are piles of paper (mostly bills and junk mail), car keys, shoes around the front door, empty cups, sunglasses, and random objects that somehow made their way from your child's school bag and onto the kitchen counter. And that's just the beginning. The dining table is another surface that tends to be a clutter magnet.
If you truly want to embrace the minimalistic look and feel, these need to be cleared, stat. Ask yourself what can be eliminated, what can be stored out of sight, and what items aren't essential; then organize according to priority. Be consistent with this process, and come back to each room every few months with a fresh set of eyes. You'll find there's more you can simplify each time. To make sure your surfaces stay clear, give everything a special spot, and stick to it.
