Fucking same. When I first learned compass directions, I mistakenly thought east was left and carried that habit for years and now I can't unlearn it.

But things I know others struggled with learning as children I got right away and didn't need to use any tricks to get. Like using your thumb and forefinger as the less than sign and turning your hand so it's an L for "less than". And I know some people who need to use that trick to remember which one is which as adults still.

Bizarre how the brain works.
