Ask HN: How do you learn English language?

This question came from my mind because I feel that my English language doesn't improve in every single day. When I was writing this question, for example, I got stuck in the middle. I have something to say, but it's hard to write it on sentences. Beside that, I fear that I have grammar mistakes.

English is not my first language. If there is vocabulary that I have never heard before, I check out on the dictionary. I tend to improve my English. Writing, listening, speaking, and reading are my goals (order means the priority). So, how do you learn English language?

Note: if you suggest books, resources, or even stories, please don't hesitate to share it.

Thank you.
