I've been learning German on my own since age nine, and Hebrew since I was old enough to attend school. Recently I learned how to read Cyrillic (understanding what I'm reading will come later), and Yiddish and I want to learn Arabic, Polish, Czech, and Hungarian.
Yeah, there just ain't enough hours in the day for all that. At most I might get fluent in German, Hebrew, and Yiddish, but at least learning how to read Arabic, Polish, Czech and Hungarian would be good enough for me.
