An affliction indeed. Kind of like a compulsive gambler with his belief that the next roll of the wheel will pan out for him, though not (necessarily) as financially crippling as gambling.

I wish I'd had the discipline to keep on with my Greek; I might still be able to read Plato. It's one of the languages I keep meaning to go back and get in shape, because hell, Greek! So much wonderful stuff to read!

But then oh! Korean! So useful! and hangul keeps getting recced as the perfect writing system! and I live in Koreatown so the linguistic envelope is there!

And I always did want to learn Swahili as well...

Arabic however is one of those languages that people like me with no ear at all shouldn't even think of, so I never did. And probably would get nowhere with Swahili because so much of it comes from Arabic.
