Many-many-many books (with a dictionary by me) and reading for hours and hours. I grew up at a time there was no internet, just books. I was lucky enough to have plenty of english books close to me. Then while in Uni (in the UK) I would (actually) read the physics/maths/electronics books cover to cover (with a dictionary by me). After the 00's it was many-many-many english-speaking movies and series without subtitles.
