Fundamental Principles Revisited
🎯 The 5 Core Principles
Clarity Over Cleverness
- Bad: “Make it pop”
- Good: “Use vibrant colors, dynamic layouts, and engaging headlines that capture attention within 3 seconds”
Specificity Beats Generality
- Bad: “Write about AI”
- Good: “Write a 800-word blog post about the ethical implications of generative AI in healthcare, targeting hospital administrators”
Context Is King
- Always provide: Audience, purpose, format, constraints
Iterative Refinement
- Start broad, then narrow based on results
- Use model feedback to improve prompts
Model Awareness
- Different models have different strengths
- Tailor prompts to the specific model you’re using
