My favorite way of learning languages.

I don't have just only one favorite way of learning English.

I have used a lot of different sourses for educationtudy resources and some different techniques.

‘Resource’ sounds more natural to me here. ‘Source’ is more often used to mean ‘origin’ or ‘where something came from’. People often say textbooks are a good ‘resource’ (= a useful thing) for studying a language.

I have a self-teachstudy book.

I a’m not sure howwhat it’s called in English.

May be "a self-education book" or something.

I use that book forto teach my selfish education English.

I watch a lot of TV- series in English,. "Supernatural" is my favorite one.

I have been watch that show many times in Russian language.

I have watched that show a lot in Russian = you watched it a lot in Russian in the past but maybe you’re not watching it in Russian anymore.
I have been watching that show a lot in Russian = you still watch Supernatural in Russian or you recently watched the show in Russian

My favorite character in Supernatural is Sam, because I'm similar with hishe has the same personality as me.

I’ve also have used a lot of different apps to study English.

I ha’ve used a GPT chatgpt and an AI powered smart assistant, Its name is called Gliglish.

Yeah I'm also not sure what you would call this. I think "self-education book" is better than "self-teach book." Maybe "a book meant for self-studiers."
