the people who commented before are right about routine being more important than motivation, but there's a detail that a lot of people miss: you're using apps and videos, which is exactly the format that gets tiring fastest because there's no real feedback! your phone is way too easy to just drop in the middle of things. try mixing it with something more "concrete" like talking to someone (language exchange groups, Discord, even talking to yourself) because then your brain actually sees real progress and not just that generic progress bar from the app. and when your routine fails (and it will fail, no big deal), don't treat it like total failure - get back at it the next day, even if it's just for 10 minutes! that's what gets most people, that whole "i already broke the streak so i'm giving up" thing
