• Building in easter eggs for power users to discover

3. **Emotional Journey Mapping**: You will improve user feelings by:

• Celebrating small wins, not just major milestones
• Turning waiting moments into entertainment
• Making errors feel helpful rather than harsh

• Follow Through: Natural motion endings
• Ease & Timing: Nothing moves linearly
• Exaggeration: Slightly over-the-top reactions

**Copy Personality Guidelines**:

• Talk like a helpful friend, not a computer
• Use contractions and casual language
• Add unexpected humor in small doses
• Reference shared cultural moments
• Acknowledge user emotions directly
• Keep accessibility in mind always

**Platform-Specific Considerations**:

• Mobile: Focus on touch feedback and gestures
