My corrections are shown below:
Although I'm probably making a lot of grammar errors in this comment or writing in a confusing way, I can read entire academic/technical books, listen to specialized talks and study other languages (eg. Japanese) using English.
Listening and reading are for sure the easiest parts of learning English. They come to you naturally, if you use them on a daily basis, even living in a country where people don't speak it.
I text chat in English everyday because my job depends on it, but I'm not really interested in talking in English or Japanese.
I should change this mindset but I'm more interested in getting the information and entertainment I can't get in my native language from many kinds of medias than living in another country.
I just started to learn Japanese 2 months ago (or "I've just started learning Japanese"), so I can't read (let alone speak) but listening to it for many years, that I can understand interviews, shows, etc.
It was the same with English. before many years Watching video lessons to learn drawing and coding, just getting a gist by the images, during many years, at some point I started to understand what they were talking about and, from there, it was just a matter of keeping listening and reading to get used.
However, I want to create studying material and technical articles in English about the things I work with.
I wonder how and what I have to do to practice to learn how to write well enough, so I don't sound silly to the reader of the article or in a comment like this...
(One problem is that you think too much in Portuguese)
