I am so glad to hear that you are planning on learning Chinese! You also mentioned that you are worried because you heard that Chinese is interesting but also really hard. You know what? Don't worry! Because I'm definitely going to help you and I promise you that Chinese worths the hard works. As a beginner, it is really important that you go buy the right dictionaryies because they will be guiding you through the language. My suggestions are "No.1 Chinese Dictionary" and "Xinhua Dictionary", because these two are the ones that I use and they are absolutely helpful. You can probably get it in book stores in your country, so go get them now and start learning Chinese! Have fun and you can always forward any concerns.
