"Running Isn't My Hobby. It's My Medicine."

Image
    "Running Isn't My Hobby. It's My Medicine." I've been reading Nexus by Yuval Noah Harari. He says humans are storytelling animals. Money is a story. Nations are stories. Religion is a story. When enough people believe in the same story, that belief becomes fact — and eventually, reality. Reading this, a strange thought crossed my mind. What if the worries I carry every day are just stories too? Sometimes, when I'm sitting still and doing nothing, an unwelcome visitor slips into my thoughts. "What if I lose my income? How would I survive?" That one sentence pulls me under. One thought leads to another, and before I know it, I'm drowning in anxiety. On those days, I'm almost afraid to go home — afraid the weight of it will seep into my wife, afraid my kids will somehow inherit this part of me and struggle because of it. But when I stop and think clearly, none of it makes sense. There's no enemy in front of me. I'm n...

Week 3 of Morning Running — Why Can't I Just Go to Bed?

Image
  Morning Running Log | Week 3 Week 3 of Morning Running — Why Can't I Just Go to Bed? At night, I can't fall asleep. In the morning, I tell myself "just five more minutes" — and the moment I close my eyes, I'm out cold. If only it worked the other way around. Out of roughly 20 days, I missed 4 mornings. Changing a habit is harder than I thought. · · · I. Week 3 — Still Feels Like Day One Morning runs still don't feel natural. Getting out of bed is a battle, and once I'm out there, it feels more like a shuffle than a run — nothing like the energy I have in the evenings. And then I'm exhausted for the rest of the day. The one good thing: the quiet pride of keeping a promise to myself. But how long can I keep going like this? "Time to get my act together." That's the real reason behind all of this. After fifty-something years, I finally understood it in my bones: words don't change anything. Only action does. So ...

[Vol. 22] Co-Intelligence Is Already Outdated

Image
  Surviving the AI Era | Vol. 22 [Vol. 22] Co-Intelligence Is Already Outdated I gave my best at work for over 20 years. My life is still tough. Living under capitalism, I never once thought about owning capital. I just sold my labor and time, believing that would be enough to get by. That delusion is exactly what made my life what it is today. I only realized this now.   Now everyone's talking about AI. I don't know much about it, but the fear of repeating the same mistake I made for 20 years—working hard while staying ignorant—has me watching every AI video I can find.   Sam Altman, Elon Musk, big-name executives talking about the future of AI. Professor Kim Dae-sik's various takes. It was fascinating. It was new. But at some point, the excitement faded. Before I knew it, my question had changed from "Wow, that's amazing" to "So what am I supposed to do?" YouTube doesn't really have answers to that question. So I turn...

Why I Finally Came Back to the Exercise I'd Been Ignoring

Image
  Why I Finally Came Back to the Exercise I'd Been Ignoring I didn't have time to run, let alone do strength work. Two years of injuries changed my mind. I. Who Has Time for Strength Training? When you go from barely running 1km to comfortably finishing 10km, there's a moment where you think: "I'm actually a runner now." Around that time, I stumbled across a term on YouTube: strength training for runners . My immediate reaction? "By the time I get dressed, run 10km, and get home, an hour and a half is gone. And now I'm supposed to do strength work on top of that? I barely have time to run." Just like that, strength training disappeared from my routine. · · · II. The Injuries Didn't Come All at Once Looking back, the injuries didn't appear out of nowhere. When 10km was my regular distance, I was brimming with confidence — a tadpole who thought he was a shark. One beautiful day, I decided to ...

Why I Decided to Become a Morning Runner — Again

Image
  Why I Decided to Become a Morning Runner — Again After two years of injuries and excuses, the answer was embarrassingly simple. I just had to wake up earlier. I. The Hunger to Run For the past two years, the pattern was always the same. Train a little, race, get injured, spend months unable to run. Recover just enough, race again, get hurt again. Despite years of running, I was going nowhere. This year, I changed one thing: I stopped chasing times and focused on staying healthy. The results? A full marathon finish. A 100km ultra finish. Both without injury. After every previous race, I'd been limping for weeks or unable to run for months. This time, I could lace up again within days. I didn't realize how extraordinary that was until I experienced it. That difference — between pushing too hard and coming home in one piece — deserved a closer look. Pushing too hard → Injury Finishing healthy → C...

[Part 21] Why It's Called the AI "Singularity" — Not the AI "Revolution"

  [Part 21] Why It's Called the AI "Singularity" — Not the AI "Revolution" AI Survival for the 40s & 50s · Series EP21 · Ray Kurzweil — The Singularity Is Nearer ··· In Part 20, I wrote this: "This time, I won't be caught off guard." So I picked up a book. Ray Kurzweil's The Singularity Is Nearer . A man who got 86% of his 147 predictions right. The man who coined the term "singularity," and prophesied it would arrive by 2045. After finishing the book yesterday, I waited for my son to finish studying. When he came out for dinner, I started talking. "Daehyun, I finally finished The Singularity Is Nearer . Want me to tell you about it while you eat?" "Sure." He'd listened with interest when I told him about Yuval Noah Harari's 21 Lessons for the 21st Century before, so I felt comfortable bringing this up too. ··· 1 What Is the Singularity? "To understand wh...
