In shared spaces, Morgenstern suggests working together to design an organization system. Don’t simply dive right in. Her motto here is: analyze, strategize, organize. Analyze: “Each of you should define the objects that are in the space that you are always looking for,” she says. “The space has to work for everybody in order for the system not to fall apart.” Strategize: Together with your family, figure out what the space will look like when it’s complete. Model it after a kindergarten classroom with similar items grouped together and activity zones (for sporting equipment, for example). Organize: Everyone can help sort and group the items, help purge, and box items up for donations before implementing the strategy everyone came up with together.
