Like me, you most likely have at least one shelf that’s full of knicknacks or memorabilia.
Declare that shelf knicknack free. Remove all collectibles, trinkets, picture frames, etc. Put these items into storage for a while. Dust or polish the shelf until it shines. Add one small vase of flowers, or a small house plant. Don’t put anything else on this surface for at least one month.
You’ll be amazed at the peace you feel with that nearly empty space.
