I’m not so experienced using memory techniques but I would like to try helping with an example of what I did for one concept specificly.
An author I studied conceptualizes “jurisdiction” as being:
“a state action aiming to apply the objective law to the concrete case with the purpose of solving a legal crisis permanently and thereby achieving social pacification.”
So I made mental images in order to help me remember almost verbatim this concept.
“a state action (a politician behind a theater curtain) aiming (a binocular) to apply (an injection) the objective law (a book with a hammer) to the concrete case (brick/concrete) with the purpose of solving a legal crisis (the contenders fighting in court) permanently and thereby achieving social pacification (people in a community with friendly feelings and doves flyring).”
The way I imagine the objects is the theater curtain opening and showing a politician that is using a binocular and seeing a flying angry injection stinging a law book so it got scared and “throw” a brick in the contenders fighting in a court room so after it the court room door opens and the community is all friendly and peace doves are flying in the sky.
This full scene is pretty silly but it is easy and fast to remember. Now only thinking about the concept needed I see somehow the objects and the concept is already strong in my mind. So yeah after studying actively and understanding the concept I create this ridiculous story for memorize it almost verbatim.
For your example I would problably use this scene:
Some people like (a couple people with joy) to pursue (pursuintg with Need for Speed™ Hot Pursuit cars) hobbies (hobbits from lord of the rings) in their leisure time (in a playground/amusment park). A helthy hobby (muscular hobbit) keeps them active (a green light as it man is active) and busy (doing a lot of work) in a productive way (in a factory).
So the full scene would be:
You see a a couple people driving need for speed cars pursuing hoobits in their leisure time at a playground. After you pass this scene you look muscular hobbit with green lights in thir back while they are doing a lot of work in a factory.
You can make all in one scene or use 2 scenes (like I did) if it make sense to you. Using a memory palece to alocate the scenes/images will make it even stronger because it will have spacial hooks too.
I would recommend you to read books, topics in this forum and pratice to get better in creating images. My images are not the best, I sure can improve it, but I believe that using the memory techniques is the best way to get better, in other words go and try yourself to find what works better to you.
You will see that with some silly images your brain will remember the text. The techniques that people help us to leran here are very powrful to remember thigns with ease.
