✅ Introduction
As I entered my 50s and started preparing for the second chapter of my life, I realized that AI is no longer optional—it's essential.
While watching various YouTube videos introducing AI, one figure stood out: CareerHacker Alex.
His approach to ChatGPT and AI was unlike any superficial overview I’d seen before. I thought, “I really want to learn this properly.”
Fortunately, I found out that Alex himself was offering a practical ChatGPT course supported by the Korean government.
Being able to take such a high-quality course at an incredibly low cost through the national “Naeil Learning Card” program was truly lucky.
So I didn’t hesitate to enroll—and now I’m confident it was the right decision.
💡 Course Summary

- Provider: FastCampus (K-Digital Basic Competency Training / Government-funded program)
- Duration: May 28, 2025 – June 16, 2025
- Why I Enrolled:
I needed structured AI learning to prepare for my second career, and I didn’t want to miss the chance to take a hands-on course by CareerHacker Alex at a low cost through government funding.
🛠️ What I Did During the Course
Understanding and Relearning ChatGPT
- In the first week, I studied how ChatGPT works and realized I had only scratched the surface.
- I experienced how "good questions yield better answers", and I began using ChatGPT not just as a chatbot, but as a productivity and thinking tool.
Prompt Engineering for Image Analysis (Week 2)
- I learned how to guide ChatGPT’s responses intentionally.
- This helped me significantly enhance an ongoing AI-based image analysis project.
Automation Tools Integration (Week 3)
- I practiced integrating ChatGPT with the Gamma app to automatically generate presentations and documents.
- I saw the potential for real-world use by auto-summarizing analysis results into structured formats.
Advanced GPTs + GitHub Integration (Week 4)
- Although the course was scheduled through July 2, I completed all core lessons by early week 4.
- I’ve since focused on advanced GPT functions and building automation tools with GitHub to prepare for AI-based content creation and blog automation.
After the Course – My Own Use Cases
- Even after the official end date of June 15, I’ll continue learning until July 2, focusing on report automation, image analysis, and AI-powered writing.
- I plan to apply ChatGPT in preparing for the national judicial scrivener exam and pursuing my dream of becoming a writer.
📝 Final Thoughts
Being able to take such a hands-on AI course through government support was a huge stroke of luck.
This wasn’t just about using ChatGPT as a tool—it was about building a foundation for generating content and automation in my own workflow.
I plan to apply this experience to blogging, automation, and image-based projects going forward.
