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?
My goal is to spend 100 minutes per week listening and also 100 minutes reading. Usually I achieve a little bit more, sometimes life is just too busy.
I also track the time spent. Seeing the progress is a good motivation for me
