I started learning Chinese out of curiosity in 2002 after I came to Germany to do my PhD. So far I have learned everything by myself, without taking any classes. I can read fairly well, my pronunciation is not bad, but I haven't achieved fluency yet and my listening comprehension really sucks. The chances of ever spending any significant amount of time in China are essentially zero, so the only option I have is to take online classes with native speakers. Last but not least, I would add that I'm married and have a beautiful four-year-old daughter.
