I usually spend 1-2 hours. Any more than that and I get too tired. At my pace it takes about a year and a half to 2 years to get to where I can read and listen. But I reckon it could be cut down if I was spending more time a day.
I heard that training diplomats spend 8 hours a day on the language they’re learning: a full time job. Imagine that. I’d be completely exhausted and my brain would be buzzing by the end. You reckon you could do that?
I also aim for a minimum of 2 hours a day. Occasionally I’ll do much more, but often my mind is pretty wiped on that language after 2 hours. It’s been one year (or a little over 750 hours) and I can read teen fiction (e.g. harry potter) and listen to some native content (e.g. kids cartoons like Pokémon). I think 2 years (or 1500 hours) I’d expect to understand most content and people without needing them to speak slowly or carefully.
My reading goal is counted in words though, I’ve only just started reading in my target language but want to read 1,000,000 words in that language over the next year on top of completing the 2 hours a day listening.
It’s also worth mentioning that listening has become far less tiring towards the end of this year, compared to the start.
To add to this, I thought I might also mention that my ability to speak is still not particularly good yet, it’s very rough and slow. I’m hoping between 1000-1200 hours of listening to see that improve as my mental model of the language fills out more completely.
Yeah speaking is always the last thing I work on too because you need a partner and I prefer to be confident in my ability to understand first.
I count my progress in words that I know. Usually around 15k to 20k is a good level to start speaking. I don’t know how much reading it takes before I get there. I suppose it depends on how new-word-dense the material I read is. It’s always a big leap going from learner material to native speaker material but before long simple texts won’t do it anymore and I start reading novels to hit my daily goal.
