Ooh, you definately have an advantage in having already learned other languages! 8D I wish I had taken another language when I was in school; Hindi is my first attempt to learn another language (and by now I have been out of school for so long that my knowledge of general grammar rules is just...stinky. 8P..). I have one other friend who is studying the same sources with me, but we don't get to meet up very often and she is also teaching herself - we need to find some Hindi speaking friends to help us along.
I also have the "your first 100 words in Hindi" book and managed to mostly learn to read the script from that (my friend got it, hated and returned it though!) before I started to read Snell's book on the script (I wish I had started with that - but I do love my 100 words flashcards! 8D...)
Hurray for Bollywood movies and film music!
