We will take on the challenge again in 2026.

December 31, 2025. As I wrap up the year, I think about the next. What kind of year should 2026 be? I hope it becomes a year where the beginnings of last year take root and new branches sprout. Four Roles. I live four roles: creator, entrepreneur, CEO, and head of the household. For each role, there are things I want to do in 2026. As a creator, I want to publish my seventh book. A lighthearted essay or poetry collection that isn't too serious.

Mahjakga's Top 10 News of 2025: A Year of Unceasing Attempts

2025, the Year of New Beginnings. The year is drawing to a close. 2025. Strangely enough, it was a year that felt fittingly "news." Rather than major events, it was a time when small yet distinct changes accumulated densely. The Yonsei University Advanced Management Program (AMP), my sixth book, an app built with VIVE Coding, parting ways with a BMW, the ketogenic diet, tennis, lessons from Simplet Q, the AI craze, and a vacation with family. Looking back, all of this converges on a single question: "How am I living my life?" Socialite

The Pride of a Publisher (Artist's Money Making)

One day, a businessman. I have three identities: one is the head of the household, another is a writer, and the last is a businessman. One day, I became a businessman. In a way, it is passive. I never dreamed of becoming a businessman or tried to start one. I also tend not to have preconceived notions about business. I do not think of business as simply money. In that sense, I consider missionary work to be business, and campaigns for a fair world to be business as well. Buddha to people

Thoughts I had while working overtime for the tenth day

A post written in February 2024. I have been working overtime for ten days straight. Today, I worked until 10 PM. Actually, it feels like it has been even longer than ten days. I haven't been able to go to my vacation home in Gangwon-do for three weeks. By "overtime," I mean working at the corporation I manage. I am pouring 901 TP3T of my time into the company. Naturally, this is not normal. Because I am engrossed in only one of my three identities, it is interfering with my life as a creator and as a private individual.

From Lawyer to Junior Editor: About a Turning Point in Life

"Is this the right path?" I worried about this a lot in my 30s. “Is the path I am walking right now the right one?” “I’m walking this because others told me to, but it doesn’t feel like my path.” “This path looks decent on the surface, but it doesn’t seem to fit me.” “Walking this path makes me feel like I’m deceiving myself.” However, few people have these kinds of worries. In my 30s, I could count on one hand the people around me

50 million won per month

Three years ago, I thought everyone would be happy if our monthly revenue reached 30 million won. So, I devised and executed a strategy to achieve that goal. We reached 30 million won. It felt like we had become rich, but nothing had really improved. We needed more people and a bigger office. Of course, I felt less anxious about the future. At least there was the cash flow coming from the 50 million won monthly revenue. Not just a few months from now, but a few years from now.

Challenging for Highest Revenue as an Entrepreneur (100 Million Won, Passive Income, and a Toast)

Reflection on My First Steps: In January 2020, I resolved, “From now on, I will support myself.” I wanted to create a lifelong career and do my own work without retirement. I wanted to build my own life, earning a living doing what I loved without being swayed by others. Up until then, I hadn't even considered things like corporations. I became a writer, and many people listened to my opinions. As an extension of that, my life as a freelancer began unintentionally. That

My Two Concerns and Mentors
