[2026 Tax-Saving Tips for Office Workers] Tax Accountant Ryu A-ra's Tax Class for Employees—Things Your Company Doesn't Tell You

The most rapidly emerging task automation tool recently is 'Claude Code.' Through Claude Code, you can deploy AI agents within your computer that work exclusively for you and create a system where repetitive tasks are assigned to the AI one by one. Try automating 100% of the once-exhausting tasks like PPTs, reports, and Excel work.

Are you using AI but still unable to get it to do the work for you? This course is not just about simple usage; it is a process of creating your own "high-performing AI assistant." By mastering everything from prompt principles to personalization settings and task automation at once, you can delegate repetitive tasks to AI and create a new way of working that allows you to focus on your core responsibilities.

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.

In the AI era, you don't need to know how to code. What matters is not development skills, but the ability to work with AI. This course is a hands-on lecture where non-developer professionals use Cursor AI to build their own tools for automating repetitive tasks. From Excel automation and document generation to webpage creation and business dashboards, you will follow step-by-step for 3 hours to complete your own results.

Are you still using Google Sheets simply like Excel? If you use Google Sheets properly, you can significantly reduce the time spent on collecting data through copy-pasting, getting confused by the latest files, and fixing formula errors. Try automatically operating reports and dashboards that are always up-to-date based on real-time data connections.

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.

Most office workers work hard on their reports. The data is sufficient, and the logic is sound. Yet, the results are always the same: - “Let’s review this.” - “Let’s supplement this a bit more.” - “Let’s discuss this again at the next meeting.” The problem isn't that you can't write. It's because the document is not designed to trigger a decision. This lecture is not just about how to write a report; it covers how to design a document according to the structure of how decision-making actually happens. Over 26 years of reviewing countless reports in major corporations and investment fields, I found one commonality from the perspective of someone who actually "makes the decisions": [Decisions come from the structure of the report, not just the content!] In this lecture, we will: Analyze where executives stop their judgment Identify what must be present for a decision to begin through real-life cases, and provide methods to transform your documents into a structure that is written quickly and approved immediately.

We don't just point out the right answer. We create standards that allow you to judge the market in the moment, even when it only looks easy in hindsight.

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.

I have prepared a basic lecture on taxes that you must know while living in this world :)

Welcome to the "dungeon" known as the data center. I remember my first day reporting to the data center operations team three years ago. Even though I was a 10-year veteran of construction and commissioning who had seen it all, I have to confess... I was intimidated. (Laughs) "Is this the same HVAC I used to know?" "If I make a mistake here, will it make the national news?" That feeling of your heart racing with half-excitement and half-anxiety—you’re probably feeling it right now, aren't you? Once I actually got into it, I realized the skills I learned while breathing in dust at plant sites didn't just disappear. However, this thing called a "data center" definitely has a different personality than a typical building; it is much more prickly and sensitive. Working as a Lead Engineer, whenever I saw juniors falling into a state of "mental breakdown" with the exact same expression I once had, I would see my own reflection from three years ago. "Man, I had to learn the hard way by banging my head against the wall, but I want to teach these guys so it hurts a little less for them." This lecture was created with that single thought in mind. I’ve already gone ahead, experienced the trial and error you'll face, and even put together a complete "incorrect answer note" for you. I have packed in all the know-how from my 17-year engineering career—mixed with my blood, sweat, and refrigerant. So, please feel free to dig in, tear it apart, and savor every bit of it. If you ever think, "What on earth does this mean?" while studying, don't hesitate to ask on the bulletin board or via email. I will come to answer you faster than a UPS (Uninterruptible Power Supply) and with more energy than an emergency generator. Now, shall we get started?

This package is an integrated bundle that combines the two existing courses of "[26 Years of Corporate Experience + Author of 4 Books] Business Report Design Methods That Pass on the First Try." - This course is a process of transforming reports from mere explanatory documents into a "structure where decision-making occurs." - Many professionals work hard on their reports, only to receive feedback like "So, what's the conclusion?" or "Let's refine this a bit more." - The problem is not your writing style or PPT skills; it is a structure that does not align with the decision-maker's flow of judgment. 🔹 Project 1: [Discovery] Making it clear why reports fail to pass Recognize the reasons for a report's failure through structure rather than intuition. - Why persuasiveness is lacking despite having sufficient numbers and data - Structures with plenty of explanation but no decision-making - The critical difference between "writing hard" and "getting approved" This is a mindset-shifting stage that fundamentally changes your perspective on writing reports. 🔹 Project 2: [Expansion & Persuasion] How to design reports where decision-making actually happens This stage covers how to translate the problems identified in Project 1 into actual report structures and sentences. - Designing structures where judgment is repeated - Creating organizational standards rather than one-time persuasion - Strategic phrasing and placement that trigger decisions This is a practical course to expand reports from explanatory materials into decision-making systems.
