My English is already C1/C2, so the default content available on LingQ is useless to me. I have to import my own content and consume it.
What is a good way to have a daily supply of English content to run through LingQ to improve my English?
YouTube channels, videos, etc.
I am learning American English.
I guess this depends on what aspects of your English you’d like to improve on. And what the reason for improving is, of course?
I want to improve my conversational English ~ to use natural sounding native-level English that is neither superfluous nor ESL-sounding.
In addition to that, I want to generally maximize my English fluency as, at least right now, it’s the only language I am working on.
I am doing accent reduction on the side, and want to use LingQ to improve my vocabulary/grammar/spoken language.
Hi there, I’m a native American English speaker from Southern California, so my accent is the same as what you’d hear in Hollywood. There’s an insane quantity of series and movies out there with this dialect/accent 
Feel free to ask if you have questions about a specific movie or series. Cheers
You should find someone good at English to improve your English fluency. On the other hand, you can join different groups where you can talk with other people. By starting the conversation with them you can increase your English fluency. You can also join in different paid English groups. They will also help you to increase your English fluency.
