Hi Alvin, as soon as I saw the title, I knew I had to read it. After reading it, I knew I had to write back a comment, not just to say how much I enjoyed reading it but also to thank you for inspiring me to write one titled, How I got obsessed with mastering Mandarin. I promise it won’t be some imitation of yours especially since our experiences are totally different. In fact, my experience in mastering Japanese (as a national who grew up in North America) is also very different albeit with unavoidable overlaps.
