You remember because you assemble things in a storytelling form. I would argue that genetically our brains are wired for storytelling. It's our method of organizing information for presentation to others. I have never known a great teacher, a great political leader or a great military leader who also wasn't a great storyteller. Education is a storytelling problem.
Leadership is a storytelling problem.
Ultimately, being a CIO is a storytelling problem. However, most CIOs don't understand that. On multiple levels. Because you're a leader of an organization and your job is to identify and articulate that vision of the organization. I often find that technology information organizations don't have a vision.
