Pro Tips for Choosing Your Topic

• Focus on the 'Why' over the 'How': A reflective essay should explain your internal thought process during a technical challenge, not just the code you wrote.
• Identify a 'Turning Point': Look for a specific moment in a project where your understanding of a concept fundamentally shifted.
• Use the Gibbs Reflective Cycle: Structure your essay through Description, Feelings, Evaluation, Analysis, Conclusion, and Action Plan.
• Connect Practice to Theory: Reference specific laws (like Moore's Law or Amdahl's Law) to ground your personal experiences in established CS principles.
• Be Honest About Failure: The best reflections often come from projects that didn't work as expected and what those failures taught you about system design.
