@aicreator, that’s one of the issues I’ve been working with also. I believe the first principle to work on is to have enough practice. If you are concerned with moving images from artificial memory to natural memory, it does take much review over time.
I’ve known the Major system for 30 years but it wasn’t until recently after applying it in daily reviews for about 3 years that numbers spoke to me easily without consciously encoding them. (I’m not doing competition intensity practice.) Then, permenent memory is a result of occasional review.
After discussing with @katiek about her characters she installs in her journey locations, I started doing the same. I placed relevant people in a palace stencil I use as a rule to traverse any room, there are imaginary characters telling me their stories as I walk a journey from my house, and I’m working on another set of people as subject pegs to apply to any palace location.
I was motivated to do that by working with the principle of the five visual components that I call SEA-IT (subject-person, enhancements of subject, action, item-object, and terrain-location). They combine to form a visual sentence which is the most vivid type of memory image possible.
When you have just one or two, the image and its ability to associate with is weak, but adding more components makes the image stronger. So when you add a subject-person to a location, your chances for interactions is greater and your memory stronger.
So, in your palace, think about writing out the location and associating it with a relevant person if possible who is dressed uniquely in their domain. They also will have a typical action you know them for. These three are strongly related. Then find a typical item-object they can act on and an appropriate background you can apply to your palace like wallpaper.
I paired up Frank Sinatra in his soft-brimmed hat with his action of singing “New York, New York.” His item-object was a 1960’s style recording microphone and his location was Times Square. In my hallway, the carpet is now the sidewalk and open area with photo-op characters and the walls form the glitzy billboards. (Frank is my NE compass point to my hallway in the NE corner of my living room. I don’t like the cube method with its barren visuals.)
Relevant associations are most important when designing a system for long-term retention. Short-term associations rely more on bizarre types of associations.
Let me know how you are doing if you try my methods. Good luck!
