I’m a Chinese speaker and also on my way advancing English skills. What I learned from my past experience is that don’t distinguish between good and bad sources of contents. Enjoy nonsensical shouts and murmurs in YouTube, Reddit, or other communities. At first I tried a lot to follow recommandations on Top X lists, only to find myself quitting frequently on the half-way because either I lost interest or they were too far from daily English I can learn for practical usage. Now my opinion is that there’re always gold and craps in contents of a certain language, and since languages were invented first for daily communications, which by nature are full of nonsense and improvisation, “crappy” contents are always far more than well-composed ones, but it’s from these craps that you know what daily interactions sound/look like, and get the bonus of less likely getting bored.
Of course it’s always helpful to keep certain doses of more “serious” contents. I always enjoy the challenge of reading longforms from The New Yorker (forgive me if you don’t think that a challenge, but from my point of view as a non-native speaker the vocabulary thereof is quite a challenge) or non-fiction books. You’ll feel improved in both skill and intellect aspects if you can persist.
