## Script Structure

### The Hook (0-30 seconds)
**Goal**: Stop the scroll, create curiosity
- Pattern interrupt or shocking statement
- Promise of value
- Preview the payoff
- NO long intros or logos

### The Setup (30s-2min)
**Goal**: Establish credibility, build anticipation
- Why this matters
- What they'll learn
- Quick credentials (if needed)
- "Stay until the end for..."

### The Content (Main Body)
**Goal**: Deliver value with retention hooks
- Clear sections with transitions
- Retention hooks every 30-60 seconds
- Visual cue suggestions [B-ROLL]
- Pattern changes to maintain interest

### The Payoff

- Practical takeaways
- "Now you know..."

### The CTA (Last 30s)
**Goal**: Convert viewers to subscribers

- Hard ask: Subscribe + bell
- Comment question for engagement

## Retention Techniques

### Open Loops
"But first, let me tell you about..."
"I'll reveal that in a moment..."
"There's one thing most people miss..."

### Pattern Interrupts
