♣ Why do you receive the same feedback every time you write? Moments when you need to write always come around. But the results are strangely similar. - In papers: "The significance of the research is unclear" - In essays: "The argument is ambiguous" - In personal statements: "There's no impact" - In reports: "I don't understand what you're trying to say" - You repeatedly hear that the structure is disorganized At this point, you start thinking: "Am I just bad at writing?" However, when I actually consult with people, in most cases, the problem isn't writing ability. ♣ The problem is 'not knowing what the problem is' Many people already write enough. They revise too. They add emotion and reinforce logic. Yet the results don't change. The reason is simple. [Because they've never learned the criteria to judge and revise their writing.] So they do revise, but they're not sure if they're revising correctly. ♣ This is how this course begins This course doesn't teach you how to write beautiful sentences. It doesn't cover how to make expressions more moving either. Instead, it answers questions like: - Why isn't this piece read to the end? - I thought I wrote logically, so why isn't it persuasive? - Why do evaluations differ when the same content is written? - Why am I still anxious even after revising? The core is one thing. [Good writing has 'structural criteria' that transcend genres.] ♣ The core of this course is just one thing [The reason writing passes is structure, not intuition.] This criterion applies not only to essays, personal statements, reports, content, essays, and novels, but also to 'writing judged by evaluators' like research proposals and dissertations. This course doesn't teach specialized knowledge or research methodology. Instead, it establishes criteria so you can judge for yourself why your writing isn't persuasive. ♣ This course is especially suited for: - Those who always receive ambiguous evaluations on essays and personal statements - Those who get repetitive feedback on company reports or proposals - Those writing papers or research proposals but can't establish structure - Those who've written something but aren't sure if they're on the right track - Those who want to judge writing by criteria, not intuition ♣ What the course covers - 5 structural criteria commonly applicable to essays, personal statements, reports, and papers - The central axis of writing that must be checked before revising sentences - The minimum conditions that separate good writing from rejected writing - Common patterns that evaluators and reviewers actually look for - Structural errors that occur when emotion, information, logic, and context are mixed ♣ How this course differs from other writing courses - It explains literary, essay, business, and academic writing with one unified criterion - It tells you **where to revise**, not 'how to write well' - It can be immediately applied in actual evaluation and review situations - It provides a blueprint that can be expanded to essay, story, novel, and practical writing This course isn't a course that makes you write better. It's a course that enables you to explain why this writing doesn't pass. ♣ About the instructor This course is conducted by Lee Si-hyeong, CEO of Angae Forest Media, a professional writer who has planned and published 3 full-length novels, and has structurally refined countless manuscripts across essays, novels, and business writing. One thing I became certain of while revising writing in the field: The reason writing gets rejected isn't a matter of talent or effort, but a state of not knowing where to revise. This course is a starting point course that establishes those criteria first. ♣ One-line core summary (very important) This course isn't a course that makes you write more, but a course that teaches you how to judge what you've written.
