Reflection-Indexing stories?

Following Chapter 4, I am trying to indexing my stories but it is not easy. Examples of indexing in the book is like some kind of propositions. I wonder whether you find an easy way to do indexing your stories. To me, indexing stories is much harder to roughly jot down past experiecnes. Schank (84pp) says, "To tell a story, you must have labeled it properly, stored it away with a name that will aloow it to be found, possibly many years later, when some process calls its name." My problem is that "it is hard to find out a story to tell through my past experiences and it is much hard to craft details of experience to bring you up to imagination." I think we need to find out our own approriate and convenient way to tell a story somehow. How do you think? Of course, theoretical knowledge like Schank's idea will be helpful to make it up all by myself in the future.
