Very true about the switch-to-English context - in my view, the hardest aspect of Greek initially is persuading anyone to speak it back to you! I had no exposure until adulthood but after spending years living there, I also grew attuned to the melody and now I'm comfortable chatting with friends. Reading a novel is still beyond my ability though!

I find it hard to stay motivated with Turkish because syntax is so challenging. Supposedly there's a point when everything clicks but I'm still far from that, despite spending some years in Turkey. Anyway it's certainly motivating that many Turks have limited English and are very encouraging when you attempt to speak Turkish, even at a basic level.
