Is there a limit to the amount of time you recommend spending receiving input each day?

There is no hard limit on the amount of input time you can get and benefit from each day. You just need to be careful of not burning out. Burnout can happen if you are getting bored with the content that you are watching but you are forcing yourself to push through it. To avoid this, we recommend focusing on content that you find interesting. Easier content is also worth a try if you are getting bored because of not understanding enough. Another reason for burnout can be if you are actively thinking when receiving input. If you are constantly trying to translate in your head, analyzing the grammar, pronunciation or vocabulary of the input you receive, or trying to hold onto new words in your head, your brain will get tired quite fast. This is more common in people who have tried learning a language before using traditional methods, and even more common in people with a lot of analytical knowledge of other languages. When you let go and learn to enjoy the ride, the difference can be as dramatic as going from feeling exhausted after 30 minutes to being able to watch 6 hours of content without problem. If you feel you can’t let go and focus only on the meaning, we recommend you initially do shorter sessions with lower level material until you get used to getting input without actively thinking about the language.
