[3/13] 2026 Goal Progress: Mindset Change

This is the progress report episode. This week I especially felt a "mindset change."

Health

Personal Training Session 8

My knee was hurting a bit, so I focused on upper body this week.

My chest is getting thicker and thicker, and my trainer is complimenting me. Happy. However, being mindful of balance, I focused on shoulders, deltoids, and triceps. Having only a buff chest would look weird.

The knee pain seems to be muscle tension from doing exercises with bad form. I resumed stretching which I'd been slacking on, and it's gradually getting better. It still hurts when I cross my legs, so I'll watch it a bit longer.

On Sleep

WBC was on, so I stayed up late a lot this week. Early rising habit is honestly disrupted.

However, yesterday and today I woke up in the 4 AM range. The problem is going back to sleep. I found that if I go back to sleep and wake up around 8 AM, my head hurts until noon and I can't switch on. Once I wake up, I should just stay up and nap properly at lunch. This shift seems better.

Also, it's been cold and hot outside lately, so I'm properly soaking in the bath before bed to regulate body temperature. Together with my son.

Work

A Step Toward What the Company Should Be

Last week, I declared what the company should aim for. This week I started taking action right away.

After doing various hands-on things internally, I got a sense that the path is visible. What we're about to do is quite difficult. But if we pull it off, it'll be incredible. Because it's that kind of thing, people in the company are getting excited. This is kind of nice.

Claude Code Is Amazing

Wednesday had 7 meetings throughout the day. Only 45 minutes of break time in the gaps. Normally a day where nothing can be done.

But with Claude Code, the story changes. Give multiple instructions before meetings, and during meetings I occasionally get "done" notifications from various tabs. Quickly approve and commit-push. As a result, even on days like that, I could put out 5-6 PRs.

The trick is breaking things into small units. Write the plan in an MD file, and proceed in super tiny steps: step 1, step 2... Clear context after each completion and move to the next step. By keeping granularity small, I barely feel hallucinations.

If this becomes normal, it's basically full automation, right?

Challenge: Review Is the Bottleneck

That said, there are challenges. Cases are piling up where I'm the bottleneck in code reviews, preventing other members' work from completing.

Simple source code changes are fine, but things that require touching infrastructure, or things I can't fully delegate due to permissions—I have to control those. That's where it's stuck.

By the way, about having AI handle infrastructure. I recently heard that someone let AI do all their Terraform and 2.5 years of database got blown away. No backups, but it was recovered because it happened to be on AWS. Terrifying. If that happened at our place, we'd be done, so infrastructure is a position where humans need to take responsibility and get hands-on.

Money

NISA Account Opening Complete

There's great news. The NISA account opening is successfully complete.

Plus, I happened to win PayPay IPO stock, transferred funds from the specified account to NISA's growth quota, and set up the accumulation quota at max limit.

Something I'd wanted to do for 3 years but had been feeling fuzzy about suddenly cleared up. Now I just need to take profits at the right timing.

US stocks keep falling, but given global circumstances, they'll probably recover once things settle. Basically not panicking. I took partial profits and made some gains, so making first profits this year is good.

English Learning for Overseas Relocation

Duolingo has continued for 70 days.

Also, while walking or outside, I'm constantly listening to Center Exam listening. From 2006 going through all of them. Going through 20 years like an exam student. I didn't do that when I was actually a student (doing it now).

I can hear quite a bit, and when content I did on Duolingo comes up elsewhere, it suddenly feels like it's sticking. I'm actively watching English learning YouTube channels too.

However, I'm starting to feel like I want to put more effort in. Personal training at once a week for one hour has been changing my body and having a really good impact on my health. English too—rather than dragging it out, getting the basics down solidly and aggressively challenging myself in situations where I'd be nervous without using English will definitely make it stick.

For technical skills too, Rust, networking, security—I need to build skills to understand these myself and bounce ideas off AI. I'm reading books and tech blogs a little bit every day.

Closing Thoughts

The most memorable thing this week was that my mindset has been changing. I think this is completely thanks to weight training.

Before, I always had headaches and eye strain, and just that would deflate my mood at the start of each day. Work gets busy, posture gets bad, head hurts, can't find opportunities to hold my son, lamenting. It's been like this for years.

But with stamina building up, feelings like "if you want personal time, just wake up early" or "there must be something you can do in 5 minutes" are sprouting. A new me who can poke at my past self saying "what are you even saying" when I'm "not feeling it today" is emerging. I think this is really good.

Next week too, properly continue what I'm continuing. The me who used to be a three-day monk has made it to month 3. I want to praise myself. I'm not the type to get self-rewards, but this sense of achievement alone is enough.

Also recently, I'm doing all my private work's ToDo management through Claude Code. I have it record things I think of, strategies, goals in documents, and start each day with "what should I do today?" Almost no more forgetting due to relying on memory. This is incredibly good.

At the same time, I think, ToDo apps and SaaS are going to be weeded out, right? In the AI era, building what you want yourself and using it is becoming the norm. I also canceled my voice input desktop app subscription and built it myself, and management apps I'm subscribed to will probably be built by myself too. The key is how to run at near-zero running cost. Tips on that are worth researching.
