Seeing all the rave reviews makes me wonder if there's something wrong with me. I am not a linguistic novice; I am a native speaker of English but a fluent speaker of Korean, I majored in linguistics in graduate school, and I've studied several languages both in university classes and on my own. But I'm having a hard time making any progress in Rocket Chinese. Eleven- or twelve-morpheme sentences are just too long for a beginner in the language. And while Lin Ping's spoken examples are very clear and easy to understand, David always sounds like his mouth is full of food and everything runs together. (I'm sure his Chinese is very good, but Chinese itself tends to sound like that to start with. It's just really frustrating.)

I bought the complete premium course and am wondering if I made a terrible decision.
