Ownership feels different after storage becomes the problem.

The trouble usually starts when a thing stops living where you use it. Once it is in the garage, the closet, the paid unit across town, its usefulness has to overcome distance and effort every single time. What you own has become something you are keeping rather than something you are using.

Check what you are storing and ask when you last retrieved any of it. If the honest answer is never, you are paying rent on a decision you have not made. Make it. Keep the few things worth the trip and release the rest without ceremony.
