1. ❌ Being vague

→ Fix: Use numbers, formats and constraints

2. 🎭 Forgetting to assign a role

Always start with "You are…"

3. 🔀 Asking for too many things at once

→ Fix: Split into multiple prompts

4. 🌍 Not specifying language or tone

"Formal Spanish", "Gen-Z slang"

5. 📝 No examples

The model guesses; show it what you want

6. 🙋 Yes/No questions when you need depth

→ Fix: Ask "explain step by step"

7. 🧩 No delimiters

Use ###, triple quotes, or XML tags

8. 🔁 Thinking one shot is enough

Magic happens in iteration
