Yes, it also feels like a lot to me, but it has become much easier to do as my comprehension has gone up. But most of that is not actually taking time out of my day. I go on walks every day, listening to podcasts at the same time. While I do chores, browse the internet, or drive somewhere, I do the same thing. This usually adds up to at least 2 hours a day. On top of that I make sure to do some reading, then try to watch a show or two in japanese on top of that.

I suppose this last year has been quite good for immersion style learning, since there wasn't much else to do except stay inside.

Of course, those with less responsibilities can spend much more time doing this, and most of the success stories where people get truly excellent results in short amounts of time are from high school or college students. I don't mind if it takes a bit more time for me :).
