I would say watching lots of content in English, using social media in English, reading books, listening to songs & translating them into your native language! But most of all, you have to speak, try to find a friend to speak with or hire a teacher for conversation lessons!

Hey. In my case Italky was the crucial thing. I had been like a dog before. Understand but couldn't speak. I was practicing in a day for few months and felt that I lost a fear to speak.

I paid for Spanish lessons. But in my own time, I consumed a lot of content: books, podcasts, articles, and vlogs. I'd say the thing that took my Spanish to the next level was joining a language exchange group on WhatsApp. The group moderators made sure that the participants stayed focused and on task, so I was practicing my Spanish and helping others practice their English in equal measure.
