To be honest, I'm not that interested in learning French. But I'm just curious, for non-native French speakers, how difficult was it for you to learn it?

I have a hard time even trying to make out the way to speak. It sounds like sort of gibberish or mumblings (No offense intended). Other languages like German are still possible for me to listen to. I can at least make out the sounds. French is nearly impossible for me to even listen to, let alone understand.
