@carljalal, you sound like an artist type. Great idea if you could do it.
I’m from the programming world. There we have a term called a stack overflow. If you fill up the computer’s memory with stuff to remember, it keeps it from doing anything else, and eventually it runs out of room and dies. The most common cause of that is a recursive process which means that it has to keep doing the same process over and over until it reaches a limit. If you don’t set a limit, you crash the computer with a stack overflow because it’s trying to keep track of all of the incomplete previous processes.
So that’s the reality of what you are proposing. Not a good outlook. Your time would likely be spent designing a mnemonic to store and then having to come up with a mnemonic for designing a mnemonic to store, and so on.
That’s very similar to memorizing verbatim text in that you have too many details. The solution would be to pick out keywords in the text you need to memorize and not worry about the insignificant parts. So, at the end of the day, it would be better to remember the important things that happened and commit those to memory if you’re looking to keep a mental diary of your life.
I don’t know what a metronome palace is but my peg systems can provide a storage place for a day at a time and then I could associate events to each of the days individually or with a story. That part I’ve done.
Try doing the system and I think you’ll have a different view of the practical side of it. Let me know because you might have a good idea that we could all use. Even thes sculptor of mega-projects Christo managed to get some of his ideas built.
