The archaeology of a household fridge is a humbling thing. Somewhere at the back there is a half tub of cream you bought for a recipe you did not make, a bag of spinach that has liquefied into something unspeakable, and three jars of the same condiment because you could never see the first two. None of this is about being disorganised as a person. It is about a badly designed system: a cold cupboard with deep shelves, where the newest items go in at the front and everything older gets pushed steadily out of sight. Fix the system and you stop throwing away money without ever having to become a different kind of person.
Work with the temperatures, not against them
A fridge is not uniformly cold, and most of our storage habits ignore that completely. The door is the warmest part and it swings in and out of room temperature all day, which makes it the worst place for milk and the right place for condiments, jams and bottled drinks. The top shelves are relatively stable and suit things that need no further cooking: leftovers in sealed containers, yoghurt, cheese, cooked food. The bottom shelf is usually the coldest, which is where raw meat and fish belong, on a plate or in a sealed box so nothing can drip onto anything below. The drawers are humidity-controlled for a reason and are genuinely better for vegetables than a shelf.
If you rearrange nothing else, move the milk off the door and the raw meat to the bottom. Those two changes alone reduce spoilage and the low-level anxiety of wondering whether something dripped.
