Find good amount materials. Your local bookstore is a good place to start, but most Chinese teaching books tend to be garbage. Chinese is not an easy language, and any book promising that you can "learn Chinese fast" are bullshit. Remember, programs with a couple audio CDs and a basic list of vocabulary aren't going to help you with speaking or writing. Most books are useless. If you do decide to get a book, though, first read reviews on Amazon.com, and remember to check your local library for your selected book before you spending your hard-earned money.
