How do I remember loci which I may not use for days, weeks, months, years?
I am a college student. I want to use the 300+ buildings on my campus as a massive memory palace. My first memory task is ancient Greek. I am starting with nouns. There are three declension, and each declension is further subdivided into several morphological paradigms. I will assign each category of noun to a particular structure on campus. So as I continue my study of the language, I can just drop new vocabulary in loci according to declension and paradigm.
My concern is that I will forget loci or run out of loci as time goes on, and the entire organisational scheme will collapse.
Should I place filler-images to hold the loci in my memory?
