Many people write. But most of those writings end up buried in files. This lecture starts from that point. ✔ “Why does nothing happen even when I write?” ✔ “How can I connect my writing to opportunities and money?” Through 26 years of corporate experience and actual writing, publishing, and lecturing experience, I have personally built a structure where writing becomes an "asset." In this lecture, I will share more than just simple writing techniques; I will show you specifically how to: 👉 Take a finished piece of writing → Expand it into blog posts/content → Build it into a portfolio → Connect it to lecturing, publishing, and business opportunities In particular, I will explain the entire flow based on realistic standards: How a single piece of writing expands into content How 5 pieces of writing become a lecture How 40 pieces of writing become a book By the end of this lecture, your writing will no longer be just a "record," but an asset that works on your behalf.

"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.
