I've got a trick! Mnemonics!
Say you have to remember a thing. Real example: When I go to camp tomorrow I have to remember to grab a bucket of gravel. Never going to see it, it's off to the side. Hell, I forgot it was there until I opened it last month. What to do now?
I took a few seconds and imagined an absurd scenario (the crazier the better). I pictured pulling up and seeing an Indiana Jones style boulder of those rocks rolling down the path and squishing my truck. It ran over my wife and splatted her, rolling over and over with her stuck to it like a scene from Itchy and Scratchy. (Told ya it was absurd!)
When I pull up, I likely won't picture, or even remember, that scene, but something in my brain will scream, "Go get the rocks first so you don't forget!" But what if I get distracted unloading the truck (which happens every damned time)? I also imagined the same boulder rolling down the trail when I turn the corner where the bucket will be visible.
Another example: I needed to remember to figure out my busted ice maker so I quickly imagined sitting down at my PC and seeing a tsunami of ice cubes flooding out my monitor into my lap. Didn't remember the tsunami, but, "Oh yeah. I need to look that up."
It works on others as well! I've met people and said, "Hi! Name's Scott. You can remember that if you picture me with a talking Scotty dog head yapping at ya." And they will never forget my name.
Whenever I post this someone comes along and explains why it can't work with a load of excuses. FFS y'all, just try it. I don't know of a brain hack that takes less effort and pretty much zero practice.
