We remember what matters to us. For example, ideas, concepts, and feelings matter because we shape everything around these things. But, how much do facts matter in comparison? To remember facts, we have to memorize the information itself rather than the metadata (information about information).

It is all about leverage, we can leverage more information by storing this metadata in memory. Additionally, metadata is a lot smaller in information content than the information itself. (it takes up less space in our minds)
