I started Pimsleur, which is an absolutely excellent language learning program on CDs. It focuses on pronunciation and conversation only, which will give me a solid base in the language. It took me about 1 month to learn the kana on my own, which I'm pretty proud of. I got a book for studying kanji, but it seems impossible. Even the Japanese guys at work told me they didn't know how I could learn the kanji. I've been using repetition.
I bought the kana version of my classes text book: Japanese for Busy People (JFBP). It's hard. It seems much harder than my thai book. But I'm having a hard time getting motivated, since I can't see how I'll ever figure out kanji. Maybe I'll quit.
