Today is very tired but I can do it

I think I wanna make friends. Because I wanna meet many foreigner.

>> I think I want to make friends. Because, I want to meet foreign friends.

My father always said me “you have to think about international and then you can have your dream.

>> My Father always tell me \"You have to think about being international and then you can have your dream.\"

So I think If I already really good in English languge, I will speak in English with many foreigner and I will learn

>> So, I think if I\'m already really good in the English language, I will speak in English with a lot of foreigners and I can learn from them.

Words to avoid:

Instead of using \"wanna\" you can use \"want to\"

and instead of using \"many\" you can use \"a lot of\"

it sound more formal ^^ and so that you won\'t get used on using \"wanna\" and \"many\" :)
