Main reason for me to learn french is probably my fascination and admiration for other languages, especially french. I also had it back in high school, which makes me want to pick up some of the basic I have learned. Apart from that, the culture food and people itself are a good motivation.
I have been to France twice; in Paris and Nice and I loved it! Especially the food. First time in Paris was with my family so I didn't really experience too much of the culture within the local community (as I only did the touristy stuff), but loved the city itself. When I went to Nice, I went to visit some friends (who are french) and this must be my favourite so far. The city itself isn't too big (as Paris) and I loved the tranquility of the city. Would definitely go back.
My absolute biggest struggle (which I tend to complain too much about haha) is the french "R". There is so much more I probably struggle with, but this one is a big one for me. I have no idea how french people manage to pronounce it so effortlessly, but hopefully I'll get there one day too!
Hope this was helpful!
