I saw a form and it said to list 10 items in a room. How can you apply it to a cube
I'll try to explain it also...
Cube has 12 edges and 8 corners. Edges have 2x12=24 stickers, corners have 3x8=24 stickers.
To mark correct position and orientation of edges you need 24 letters, the same with the corners - 24 letters. How you position letters is up to you and there is almost no wrong way to do it as long as you can identify which letter means which position.
To memorise a cube you need to remember a sequence of letters in two strings - edges and corners. If you want (quicker) easy way then you have to remember twisted pieces also, but you can do it the cowboy way - start a new cycle for every twisted piece.
If you can generate that sequence of letters by looking at the cube then you pair them up and come up with the word/person/item that relates for you with those two letters.
(make up a word on the fly during memorization or take the words from your prepared list).
Depending on the scramble and the way you handle it you can have around 10-13-15 letters for edges and another 5-6-9 for corners. Maybe more, maybe less depending on luck also.

Let's say you happen to have 12 letters for edges and 8 for the corners. Instead of 12+8 letters you remember 6+4 items/persons/countries whatever works for you.
It's not enough just to remember a pile of random things - you must remember them in certain order to come back to the same string of letters which brings you back to sticker positions and helps you to solve the cube blindfolded.
To remember in order you prepare a room in your mind (or a journey or a building) that has a certain order of locations. You may invent the castle, cave, labyrinth or use any rooms/routes you are familiar with. Just with enough locations (slots) to place the items into.
Several examples have been given. What do you have in your living room? Sofa, coffee table, tv, ceiling lamp, flower pot, pool table, carpet? See, you have locations for 7 items, representing 14 letters. That should be enough for edges. Put the corners in bedroom, office or school gym. If you don't have pool table in your living room, take a different thing you have, buy a pool table or imagine one.
Just decide what to use and start training. Take a 10 page book "3 pigs" from your younger sister or son and place the items on those pages. You must learn the locations by heart anyway - room, route, book, song, whatever you decide to use.
