For all your items that have a shorter shelf life, like eggs + yogurt, place on center shelf so that you don't forget about them. This shelf is also where you should place any daily essentials- breakfast items or snacks u reach for regularly. For example, have fruit that's already cleaned, washed, cut, + ready to eat. Center shelf is also a great storage spot for leftover. Designating a place for them, will help you remember to eat what's there before you add to it.
