Not everyone has this instinct. There are many people who are unable to differentiate left from right. For those people, this doesn’t really work. I’m in my thirties and I still give shitass directions because I suck at telling left from right. I can do cardinal directions pretty well as long as I have a reference like some mountains, but like, I still have to think about left versus right.

I posted this elsewhere in this thread, but the only thing that’s ever worked for me was the right hand rule, where you use your right hand to physically demonstrate to yourself which way a screw needs to go.

Also, TIL that there’s a specific term for this: https://en.wikipedia.org/wiki/Left-right_confusion
