Future Teacher

I can't believe, that I will be an English and Chinese teacher in 5 years! However, I don't feel like a teacher now and even want to hire a tutor because I think I have a terrible pronunciation. By the way, is there someone who is ready to help me with it? I will be very appreciative.
And what about Chinese?. Is it as difficult as everone says? I have all chances to check is it difficult how everybody says or not.
My studies start on study starts 1 September, so wish me good luck.:)
