Take inventory. For now, start writing down everything that's in your drawers and cabinets on sticky notes. You don't have to do this all at once — leave the notes handy and scribble things down during those spare minutes while you're waiting for the oven to preheat. Stick them on each corresponding drawer and cabinet. It sounds silly, but trust me, simply writing these things down will help you see where you've stashed things in inconvenient spots and identify the items that are useless to you.
