Clutter leads to waste: and that's why it's so important to cut back on it now. Start with that pantry of yours. There, you'll find stuff that expired at the turn of the century. Arrange your shelves in a grocery-store fashion. Start by organizing food into categories; place frequently used items at eye level. Now, go further: create groups in the groups. For instance, in the pasta section, separate the rice, the tortellini and the spaghetti. Food is a gift: cherish it.
