Many office workers are failing to properly protect their hard-earned money because they miss out on refunds they didn't know about or pay more in taxes than necessary. Studying taxes is not about memorizing difficult legal knowledge. It is the most practical form of financial management—understanding your pay stub and protecting your own money.

Point 1. How to protect your salary through year-end tax adjustments - Understanding tax-free items and deduction structures in your pay stub - Year-end tax adjustment strategies to increase refunds, such as personal and housing deductions Point 2. Tax strategies for managing income safely - Understanding the tax structure you need to know when additional income occurs - How to legally save on taxes when filing global income tax Point 3.

This course is a lecture that focuses more on 'what attitude to invest with' rather than 'which stocks to buy.' Through questions from Ahn Seung-chan, who runs the 1.3 million-subscriber YouTube channel <Understanding: All the Knowledge in the World,> and answers from Kim Hak-kyun, a 30-year veteran analyst and Head of Research at Shinyoung Securities, we deliver the most important criteria for investing. Center Head Kim Hak-kyun, who has experienced both market booms and crashes for over 30 years, organizes the investor's mindset based on practical experience—covering the history of stock indices, human investment psychology, the power of compound interest, and investment habits that never fail. This course is not about flashy techniques, but a process of building investment principles for long-term survival.

This lecture does not view investment as a matter of "stock picking," but rather starts from understanding how asset prices have been formed and changed over the long term. It summarizes the essence of the 21st-century investment environment, created by the combination of ultra-long-term asset price trends, changes in currency value, and the structure of technology and hegemony. It provides investment criteria based on the shifts of the era, enabling individual investors to make judgments without being swayed by short-term trends, even in a highly volatile environment.

Wars, conflicts, and shifts in alliances happening around the world are no longer stories of distant lands. We are now in an era where these changes directly impact exchange rates, interest rates, industries, and the personal investment environment. Instead of consuming international affairs as "difficult news," this lecture starts by understanding why these conflicts recur and where capital moves as a result. To ensure that individual investors do not lose their way amidst global uncertainty, Professor Park Jung-ho provides an investor's perspective on reading the world order.

Dozens of economic news stories pour out every day, but it is not easy to determine what they actually mean for your salary and assets. This introductory course focuses on reducing the frustration felt when you don't know much about economics and organizing the criteria for interpreting the economy all at once. Rather than learning basic concepts like interest rates, prices, and the business cycle in a difficult way, we focus on explaining why they are important and how they are connected.

"In the early 2000s, when I first set foot in this industry, bookstores were filled with nothing but books preaching 'principles.' While you actually need to see the forest in the field, those books were busy talking about the cell division of tree bark. In that state, I was dropped into the middle of the deserts in Qatar, the UAE, and Saudi Arabia, learning HVAC the hard way by 'hitting the ground running.' (The sweat I shed back then could have probably created an oasis.) Later, when I moved to a data center and sat as an interviewer, I was surprised to find that many applicants still couldn't see the 'forest,' just like I couldn't 10 years ago. Out of frustration, I thought, 'I might as well set the stage myself,' and that's how I created this course. This is a 'condensed practical summary' of everything I've realized through 17 years of hands-on experience. Don't struggle as I did; use this course as a 'cheat code' to level up with ease. I always welcome your curiosity. The Q&A board and my inbox are on 'infinite standby,' open 24 hours a day."

♣ Why do you get the same feedback every time you write? The moment you need to write always comes. However, the results are strangely similar. - In theses: “The significance of the research is unclear.” - In essays: “The main point is vague.” - In resumes: “There is no impact.” - In reports: “I don’t understand what you’re saying.” - Repeated comments that the structure is "distracted" or "unorganized." At this point, you start to think: “Am I just bad at writing?” However, in actual consultations, in most cases, the problem is not your sentence-level skills. ♣ The problem is that ‘you don’t know where the problem is’ Many people already write enough. They even revise. They add emotion and reinforce logic. But the results do not change. The reason is simple. [Because you have never learned the criteria for judging and revising writing.] So you fix it, but you have no confidence in whether you are fixing it correctly. ♣ This course starts here This course does not teach you how to write pretty sentences. It does not cover how to make expressions more moving. Instead, it answers questions like these: - Why is this piece not read until the end? - I thought I wrote logically, so why isn't it persuasive? - I wrote the same content, so why are the evaluations so different? - Why do I still feel 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 standard applies not only to essays, resumes, reports, content, personal essays, and novels, but also to ‘writing judged by evaluators,’ such as research proposals and academic theses. This course does not teach major-specific knowledge or research methodology. Instead, It establishes the criteria for you to judge for yourself why your writing is not persuasive. ♣ This is especially for those who: - Always receive vague evaluations on essays or resumes - Get repetitive feedback on company reports or proposals - Are writing a thesis or research proposal but can't get the structure right - Have finished writing but aren't sure if the direction is correct - Want to judge writing based on criteria rather than intuition ♣ What we cover in the course - 5 structural criteria common to essays, resumes, reports, and theses - The central axis of writing that must be checked before fixing sentences - The minimum conditions that separate good writing from rejected writing - Common patterns that evaluators and judges actually look for - Structural errors that occur when emotion, information, logic, and background get mixed up ♣ How this course differs from other writing courses - Explains literature, essays, business, and academic writing with a single standard - Tells you **where to fix** rather than just ‘how to write well’ - Can be applied immediately in actual evaluation and judging situations - Provides a blueprint that can be expanded to essays, stories, novels, and professional writing later This is not a course to make you write better. It is a course that enables you to explain why your writing is not passing. ♣ Instructor Introduction This course is led by Sihyeong Lee, CEO of Angaesup Media, a professional author who has planned and published 3 full-length novels and has structurally refined numerous manuscripts across essays, novels, and business writing. One thing he became certain of while fixing writing in the field is this: The reason writing fails is not a matter of talent or effort, but the fact that the writer does not know where to fix it. This course is the starting point that establishes those criteria first. ♣ One-line Summary (Very Important) This course is not about making you write more; it is a course that teaches you how to judge the writing you have already done.

Dear Inflearn students, I’m sure you have many concerns about coding, but you likely have many concerns about marriage and childbirth as well, right? You might want to get married and have children, but the responsibility feels heavy, and you may worry about losing your current freedom. I used to be someone who was against marriage. I praised a life of freedom, but at my wife's persuasion, I chose to get married, thinking, "I'll give it a shot." At first, I regretted it because it felt like marriage was taking away my freedom, but strangely, once I let everything go and dedicated myself to my family, I became free. And I began to see the advantages that I couldn't see before due to my prejudices. This course "explains" what marriage and childbirth are to those who are hesitating. I also shared thoughts on realistic concerns, such as what kind of person you should marry and whether money is absolutely necessary for marriage. Because I was once against marriage, I was able to organize these thoughts better from both perspectives. There will likely be stories here that you won't easily hear anywhere else. In the face of the most important life decisions—marriage and childbirth—this course will be a truly worthwhile investment.

In the previous lectures, we designed the structure and removed the factors that hinder decision-making. Now, only one thing remains: Completing a decision request form that is ready for submission. Many practitioners understand the structure. They even eliminate the noise. However, they freeze the moment they sit in front of their PC. How should the table of contents be arranged? Where should the conclusion be placed? How should the options be organized? What should catch an executive's eye first when they scan the document? This lecture covers that final step. I have observed the difference between "documents that lead to a decision" and "documents that end in mere review" countless times in actual investment review documents, strategy reports, and M&A proposals. The difference was not a grand strategy, but the method of assembly. Even with the same content, the speed of decision-making changes completely depending on how it is arranged. In this lecture, we will cover: - Decision-Ready document structures - Arrangement principles for Zero-Revision - Structures that pass an executive's scan - Conclusion-centered assembly methods all with practical examples. By the end of this lecture, you will not just be completing a simple report, but you will be able to create "A document that requests a decision." A report is not about delivering information; it is a request for a decision. This lecture is the stage where we fit that final puzzle piece.
