Huge effort!

Ok people I'm doing a plan for learning english in the fastest way possible. I'm putting reddit, chatgpt, google, youtube, subnautica and my phone all in english. I'm rewriting my notes and papers on english and I would take my new lecture notes all on english. I would watch a series of english all the year and study math with english videos. I would read a wikipedia article every day and take courses of english every saturday. I'm hispanic and in a hispanic country but I want to do this on this way for fastest improves. What more can I do? suggestions? thank you!
