Textbooks teach you grammar. YouTube subtitles teach you how people actually speak. I download subtitles from native content and study real language.

For each language, I find native YouTubers I enjoy. I download their subtitles, study the vocabulary, note colloquialisms, and review while watching. It's immersion without moving abroad.
