Problem: Items shoved in the back of the pantry are never seen or heard from again.
Solution 1: Put things you rarely need back there, like extra mixing bowls and rarely used appliances and serving pieces. Label the front of the shelf to remind you that those things are back there.
Solution 2: Invest in having some drawers installed. My "pantry" is actually just a deep freestanding cabinet, and I am saving up to install drawers that roll out like the ones you see in this image.
