Pro Tips for Choosing Your Topic

• Use the 'Borton’s Model of Reflection' (What? So what? Now what?) to structure your narrative flow.
• Always link your personal experiences to established engineering standards like the NSPE Code of Ethics.
• Don't shy away from discussing failures; in engineering, analyzing a failure is often more valuable than describing a success.
• Quantify your reflections where possible—discuss specific tolerances, budget constraints, or performance metrics that influenced your thinking.
• Identify the specific 'pivot point' in your project where your understanding of a technical concept fundamentally changed.
