Shift your attention from the photographs on your walls to other decorative pieces. Do you enjoy the framed artwork on your walls? Would you prefer more empty space on your walls, or would you like to rearrange or change out some of your artwork?
Just because something’s been hanging in a certain spot for a while doesn’t mean it needs to stay there. Even if you don’t want to get rid of a piece, if you’ve been looking at it for years, tucking it out of sight for a while could reinfuse your enthusiasm for the image.
