" Not sure what you use and what you don’t? Here is a tried and true way to find out. Empty the contents of your kitchen utensil drawers into a cardboard box. For one month, only put a utensil back into the drawer if you take it out of the box to use it. At the end of the month seriously consider discarding everything that’s still in the cardboard box. Face it: If it’s still in the box after four weeks, you don’t need it! "
