French is my next choice, since for me it’s the mirror image of German.
I had a little bit of French at high school, and I had a similar amount of German instruction when I started university a few years later. We had records for French (that I refused to listen to). We had a series of 20-min films to view for German.
The difference lay in my attitude. I was disinclined to learn French, but happy to learn German.
My attitude about French has changed. So I’d like to see if my French improves as quickly as my German.
