I’ve been using Duolingo to learn a language for a few years now, enjoy it, and feel that I continue to progress. I know there are other apps out there as well but I don’t have any experience with them. Duo does have a gamification component to it — some of which you can disable, but not all — and there is a cost if you choose to subscribe.

For me, though, I’m likely going to need to immerse myself and/or take a few formal classes to get better at conversational speaking as I keep learning. Not many folks around me learning German. The app does help practice conversations and give tips, which is nice, but using a language in real life with another person is more effective for me.

Don’t let perfect be the enemy of good.

Maybe finds a few you like and make a playlist, then just watch those specific ones? Something that you can mentally focus on when in bed with your eyes closed, but also something that’s not competing to hold your visual attention as well as no giant volume swings for your audio attention. Don’t want to fall asleep to quiet dialog only to be woken by the shootout in the next scene, or fall asleep to a mellow ballad and awoken by a rock track, for example.

Edited to add: around getting bored with it— I have changed what I listen or watch every few years, but it’s a very slow ramp up of new and ramp down of old. Something your brain recognizes and likes, but isn’t trying to stay awake to read the next page or see the next episode or upcoming challenge or whatever.

Train yourself. Pavlov’s sleep. Every time you go to bed, watch/listen to the same thing. Eventually, your brain associate the thing with “time to sleep”. That’s how it works for me, anyway. I turn on the same movie and pass out in minutes. Don’t do it with one of your favorites, though.

And also, don’t do things like lay in bed watching TV or messing with your phone all the time. You want the bed to be mostly mentally associated with sleep
