We often have difficulty deciding which items we want to store and which ones we want to display. We don't always do the best job when it comes to organizing things. We often keep things that we don't need or that take up space, instead of using them or getting rid of them.
When you run out of storage space, the only reasonable option is to either clear out your belongings or rent a storage unit that is specifically sized for what you need. If you use a storage unit for some of your "hideaway" items, you can free up space in your home for more essential items.
