Practical Examples

• Example 1 (Tree of Thought): Instead of "How do I increase sales?", use: "Explore 3 different strategies to increase sales for a local bakery (e.g., pricing, marketing, upselling). Evaluate the pros and cons of each, and then pick the best one and write a 1-week action plan."
• Example 2 (Persona Chaining): Prompt 1: "Act as a creative writer and write a sci-fi short story." Prompt 2: "Now act as a strict editor. Cut this story by 30% and make the ending darker."
• Example 3 (Self-Reflection): Prompt: "Write a Python script to scrape a website. [After output] Now, review your code for potential IP-banning issues and rewrite it to include delays and error handling."

Pro Tips

• Expert Tip: Combine techniques. Use a Persona + Chain-of-Thought + Negative Constraint. (e.g., "Act as a math tutor. Think step-by-step. Do not give the final answer until the end.")
• Common Mistake: Using too many techniques at once for a simple task. If you just need a synonym, don't use Tree of Thought. Match the technique to the complexity.
• Best Practice: Build a "Prompt Library" in Notion. Whenever you use a technique that yields amazing results, save it as a template with bracketed variables [like this] so you can reuse it instantly tomorrow.

Statistics

• Quality Boost: Using Few-Shot prompting and Chain-of-Thought improves AI accuracy by over 50% in logical tasks.
• Efficiency: Professionals who use saved prompt templates save an average of 45 minutes per day compared to typing fresh prompts.
• Market Value: Prompt engineering is currently ranked as one of the top 3 most in-demand tech skills globally.
