What are the most insidious language-learning habits that silently sabotage progress?

I'm sick of the same old advice that never actually fixes the real problems. Looking for concrete, battle‑tested tips to stop the habits that keep me stuck.

• Relying on passive exposure alone – binge‑watching foreign shows without active recall feels productive but adds almost nothing to vocab retention.
• Over‑mixing input and output – trying to speak before a solid grammatical foundation leads to fossilized errors that are hard to unlearn.
• Spaced‑repetition neglect – cramming new cards each night and then ignoring the review queue creates a false sense of progress.
• Chunking without context – memorizing isolated phrases without linking them to real sentences makes retrieval flaky.
• Language‑learning fatigue – treating the process like a hobby instead of a disciplined routine leads to irregular study windows and loss of momentum.

Anyone willing to share the exact adjustments that turned their plateau into a real lift? Specifically:

1. What micro‑changes stopped you from falling back into these traps?
2. Any tools or schedules that forced consistency without feeling like a chore?
3. How do you measure if a habit is actually helping or just giving you a dopamine hit?

Drop the generic "just practice more" and give me the gritty details.
