Where is your data on Chinese not being "that" hard? According to US Military studies it's about 10 times as hard to learn as another Germanic language. In my experience, being fluent in two languages and learning Chinese, it's crazy difficult. Everybody has difficulty with different aspects of the language, for me pronunciation and tones are easy, but the ambiguity and "same soundedness" of the words really makes it difficult for me to remember anything. I know that if I put as much effort into learning German as I have Chinese, I would be pretty fluent by now. Instead I'm a still complete newb.
