Yep, that's it. You have the closet rod holding every piece of clothing you can cram in there, then add boxes of books and weightlifting weights to the shelf above the rod, eventually you exceed max weight.
I built some very nice systems in the wifes walk in closet (built the closet as well) and in her new pantry. I was looking in the pantry yesterday and will be spending some time re-orginizing today. Have to "Use" the space provided.
My wife is a stacker. If there is an open area it gets filled up.
