Technique of memorizing the Quran

my name is Abdullah. I'm currently learning to memorize the Quran. I discovered an excellent method for memorizing the Quran verse by verse. It is a method in which you create "associations" for each word (letter or sound) in the Quran. First, I would create a route for memorizing all of the visual(objects) "associations," so that on the first point (for example, the entrance to my house), there is a Quran or a person pointing up in the air, and that is my "association" for Allah (Subhana wa ta'aala), and then when I remember that someone was pointing up in the air, I immediately know that I have to say, Allah. And, yes, I am aware that associating with Allah (Subhana wa ta'aala) is a shirk, but this is different; I am associating with the word or name "Allah," not with the actual Allah (Subhana wa ta'aala). Also, keep in mind that I don't just use this technique to memorize Allah (subhana wa ta'aala); I use it for all of the words, letters, and sounds in the Quran. Is this technique permissible in Islam?
