That's how I learned it, too. Of course, even though I don't write longhand much anymore, there's still a callus on my middle finger from holding a pen a lot, so I can tell my left from my right by that if nothing else. Though I haven't been confused by it in, well, decades now. (Female; right-handed.)

On a more serious note - I tend to give directions using north, south, east, west. I think it's more clear as one doesn't have to worry as much about every subsequent direction getting screwed up if they mess up one. And I use street names for clarity. My wife hates it though. She prefers, "Turn left on the first street past the gas station."
"Now everyone was giving her that kind of look UFOlogists get when they suddenly say, 'Hey, if you shade your eyes you can see it is just a flock of geese after all.'"
