Video topic: [topic]. I want this YouTube video to keep viewers watching to the end.

Write a script that:
- hooks the viewer within the first 3 seconds
- keeps curiosity high with open loops
- inserts a pattern interrupt every 10-15 seconds
- combines storytelling with suspense
- adds lines that pull viewers back in where they are likely to drop off
- closes with a strong call to action that sounds natural

Then mark the moments where viewers are most likely to leave, and explain how to fix each one.
