1. Associate the locking of the door with emotions and vivid imagery - before you lock the door, try to remember the feeling of worry you get when you aren't sure whether you've locked it or not. Immerse yourself in that feeling, making it as close to the genuine emotion as possible, then associate that worry with some vivid image of whatever bothers you - burglars attacking the house or something - then, as you lock the door, tie that in with your imagery, like the burglars running into the door's lock. The point here is to try to associate the worry with the memory of locking the door, so that when you start to worry about it, the memory is triggered.

Or, y'know, just write it on your phone or something :D

1. pull the phone out anyway, saying that you really want to record something he said. Alternatively, ask the friend to email you a link to the book, while still resolving to google it yourself, to increase your charges.

2. Practice opening the fridge, getting something out, and closing it properly several times. Associate this with the same type of emotional link/vivid imagery. Maybe make a game out of it, flicking it closed with your foot like a martial artist kicking a bad guy. Write a not on the door in big lettering "Close me properly!" with a picture of someone staring at you. Maybe mix this with the imagery - have the picture be the bad guy you're trying to kick, or have the picture on the inside, and you're locking it in.

3. Definitely just write it down here.

4. Link each section of the speech to a stage of a narrative or something? Maybe a movie/Book you know well? I'm not really sure what would work here, I normally just wing it and it works.

5. set aside 30 minutes you fill it in in a form over and over again, taking it out and outting it back every time. That, or just let the two weeks happen with the wallet and the switching. If you have an anki deck or some other kind of SRS, chuck it in there too.

6. Have a little whiteboard or something on the wall next to your bed (check to see if glow-in-the-dark markers are a thing). Yes, this is something I have always wanted to do :P

7. Umm... drill yourself beforehand with flashcards? That much info with that little notice is tricky. Prioritize! Focus on the most important data.

8. Write it all down, mindmap it out (doesn't have to be on paper). maybe use workflowy or something for zoomable focus. Once you've figured out how it organizes, SRS/Anki is king here.
