First, because it was required of us. Part of the curriculum, you see. Then, I got hooked up with Nihongo due to Anime but got no one to talk to so it was a bit unproductive (talked to myself most of the time that everyone who heard me thought I've gone barmy). Few years after, I relocated to an Arabic country and basically it's a must that I speak Arabic yet, I'm still hopeless at it. It's not that hard but I found that there are languages close to your heart that wanting to learn them come easy unlike others that even if you gave your hardest you'd still find yourself back to square one.
