What's your biggest blocker to writing in your target language daily?

Been a few months since I launched Korean Diary AI here, and I'm still tinkering with it based on what learners actually struggle with.

Curious what this community thinks: what's the #1 thing that stops you from writing in your target language every day? For me building this, it was the feedback loop — if a correction takes 24 hours, the motivation (and context) is gone by the time it arrives. That's why I built this around getting corrections in seconds instead.

Would love to hear what's worked (or hasn't) for you, regardless of which language you're learning. 🙏
