Start with a short practice script
Make a 45-second video from this practice script, with English narration and captions. Cover every point; retain the name and numbers. Script: “Welcome to Focus Desk. Today, spend 25 minutes on one task. Close notifications and keep only the material you need. At the 10:30 review, write one sentence: What did I finish?” Focus Desk is a fictional workshop. Use clear diagrams, no extra claims.
