I will try my best for a nice trip abroad

Let me write for my second time_ in notebook.

Despite the fact that I started italki two days ago, I have already contacted some foreign friends (you do not need to repeat italki again because it has already been said in the sentence). I spent a good time(this sentence can be said better) and I am so happy because everyone is kind to me and even teach me English. I don't want to waste their helpfulness for me. So, I decide to write their advice in the notebook that I bought today (not in italki).

By the way, I paid about one hundred thousand yen (¥100,000) to the airline company as travel expenses. I must appreciate my parents because I'm still a student in a / at university (i.e., I don't work yet).

In order to not waste both the advice in English of foreign friends on italki and support of parents, I will try my best!

New expressions in English for me (e.g., word, phrase, grammar...etc);
(I'm going to write it after the above sentences is corrected)

I write on note book for the first time

Hello! Nice to meet you. My name is Hiko.
I was born in Japan, and live in Japan now; also, I'm currently studying at university. Therefore, I'm a native Japanese speaker.

In this  (<- you only need to use one or the other, so In Sep. or N) September, I'm going to travel to Australia in Europe for about two weeks as an international student. I'm nervous now because I have never been to a foreign country and I'm not good at English. In particular, I only have  poor speaking and listening in English. Even though I said this, I'm not used to writing and reading in English.
So, I'd like to write (you do not need something) in English on note book in italki as much as possible to practice my English. If my sentences in English have mistakes (improper word, grammar error...etc), could you please correct my sentence? Can I start you off with sentences on this note book?

Finally, I hope that I can connect with a foreigner on italki.

This is basically what you would ask! "Are you already preparing my ____?" "If you have not started making my ___ yet, can I change my order?"
