Figure it Out

We live in a big, beautiful world.

So many interesting things. So many unknown things. So much to learn.

So much to be curious about.

Yet, The World tries to steal your curiosity.

“Don’t think about that. We’ll take care of it.”
“Don’t wonder about that. We’ll do it for you.”
“Don’t look into that. We’ll tell you how it is.”

One quality that will keep you young, make you happy, and help you remain useful is curiosity.

Never stop thinking. Never stop wondering. Never stop looking into it.

Figure it out.

More and Less

Deep down, you know.

You know that more outrage doesn’t help you. It helps them.
You know that more scrolling doesn’t help you. It helps them.
You know that being more offended doesn’t help you. It helps them.

If your goal is to help them, then by all means.

But if not, maybe less is better.

The Effort of The Flow

I’m sure, or at least I hope, you know the flow state.

It’s that beautiful moment of full immersion, where time vanishes, doubt disappears, and the doing comes effortlessly. 

For me, it can happen when writing code, writing words, or building a spreadsheet. But also, I can find it when sharpening the knives, fixing the lawn mower, or wrestling with a jigsaw puzzle.    

I don’t find it every time I do something on that list or every day. But I’m always in pursuit of the flow. 

How do we summon it?

It’s not a sudden spark or a lightning bolt. It doesn’t hit in the shower or the middle of the night. 

It shows up when we show up. 

Steven Pressfield talks about the muse and how she shows up because you summon her. She doesn’t show up because she feels like it. You’re not waiting around until she shows up. You sit down and do the work. That’s when she shows up. 

The Flow follows effort. It’s a pattern. A rhythm. Deliberate.

The Flow finds you because you put in the effort. 

Show up. Do the work. Make bad stuff. Get punched in the face. Make it again. And again. 

Summon The Flow.

Still Becoming

People at my age often stagnate.

And just as often, it’s on purpose. They’re tired, or feel like they’ve earned where they are, or feel done.

I don’t blame people for this. We’re 30 years into our careers and probably 20-30 years into family life. We’ve been there and done that. We’ve figured some stuff out.

However, you’re also never done.

The world keeps shifting. Technology and culture keep marching forward. Changing around us, if not with us.

You keep shifting. Physically, mentally, and emotionally. Whether you’ve embraced it or not.

You’re still becoming, whether by default or design.

The question is: Are you happy with who you’re becoming?

You and Your Brain Still Matter

Apple just published an interesting paper. 

The TL;DR:

Current Large Language Models (LLMs) and Large Reasoning Models (LRMs) still suck as the complexity of the problem increases. Also, adding more resources (i.e., compute power, etc.) and better instructions don’t help. They simply hit a wall.

What does that tell us?

That AI still doesn’t think. Not the way we do. It can mimic, compute, pattern match, and summarize. But reason, connect, and leap? That’s still ours to do.

That your brain is still your best asset. For now, no model outthinks a thoughtful human, especially when problems get complicated. Critical thinking is still job security. Humanness is still job security.

Will this change? Will the models get more human-like? 

Maybe, but maybe not. AI will get better, but what better means is not yet understood. 

For now and the foreseeable future, you still matter. Your brain still matters. Your humanness still matters.

Knowledge Isn’t Learning

We confuse the two all the time. 

Knowledge is what you know. The dates, specs, and procedures. The contents of a book, the lecture, a YouTube video, or what you see from the stands. You can gain knowledge without ever leaving your chair. 

Learning is what happens when you engage. 

You can memorize the rules and strategies of chess, but what happens when you start playing? One gives you information, the other, transformation.

You can know everything there is about fitness and still never work out. You can know the steps of a sales process and still never close a deal. You can know leadership principles and still be a lousy leader.

Because knowledge doesn’t necessarily affect behavior.

Learning shows up in how you act, how you adapt, and how you grow. It shows up when you fall, reconsider, revise, and try again. It’s the shift in how you see the world, not just what you can recite from it.

Knowledge might help you join the conversation at a dinner party, but learning is what makes you worth listening to.

Costco Membership IDs Don’t Work for TSA

Despite some rumors, your Costco ID will NOT work at the airport.

The Costco card indicates you’re part of that club, but that club doesn’t carry any weight at the airport.

We all carry various physical, intellectual, and emotional membership IDs. The key is to know which one to use when.

The Sedation of Busy Work

Deep down, we know what the real work is.

The phone call. Reworking the pitch for the umpteenth time. Redoing the research and the numbers. The thing that might not work.

But we don’t do it. Not right away.

Instead, we clean our desk.
We tinker with the fonts and images.
We attend a meeting that doesn’t need us.

It feels productive.
It feels like progress.
But it’s just sedation.

Busy work dulls the discomfort of real work.
It keeps us feeling safe, but not moving forward.

The real is scary. Uncertain. We might fail. We might be told we stink. We might be told we don’t have anything.

But it’s the only work that matters.

The rest is just anesthesia.

Are you doing the real work, or are you just staying numb?

Reactor Reboot: AI and the Return of Nuclear

I live about 70 miles east of the infamous Three Mile Island nuclear power plant. It’s been shuttered since 2019.

“Exelon announced in 2017 that it would shut down Three Mile Island Unit 1 unless the state stepped in with a financial rescue of about a penny a kWh, less than half of what renewables get in subsidies even though renewables generate a fraction of the low-carbon electricity to the region that TMI does.”

But it’s about to get turned back on in 2028. Under a new name, of course — The Crane Clean Energy Center. Marketing at work here. 

Microsoft is doing it. For AI. 

And Microsoft with TMI isn’t the only one. Meta’s keeping the Clinton nuclear plant in Illinois from shutting down, and the US government is turning back on the Palisades nuclear plant in Michigan for the same reason — AI. These won’t be the last. 

Let that sink in.

For all of the cocktail party discussions and public debates about clean energy and BBQ picnic arguments around the pros and cons of nuclear, AI’s making it happen. Pragmatism steps into the ring and he’s looking well-trained, in-shape, and a force to be reckoned with.

Sometimes, you shouldn’t look a gift horse in the mouth.

On Big, Medium, and Small Decisions

You easily recognize the size of some decisions.

Marriage is easily recognized as big. Renting an apartment you’d probably call medium. And where you’ll eat lunch you wouldn’t think much about.

In the moment, or the lead-up to the moment, you may recognize the size, but it’s also just as likely that you won’t or you’ll get it wrong.

Maybe your lunch was tainted, and it put you in the hospital. Or, while eating your lunch, you serendipitously met your future partner, employer, or largest customer.

The reality is, size isn’t always measured by effort or emotion in the moment. Some big decisions feel small when they’re made. Some small ones echo for decades.

That job you took because it was convenient.
The person you met because you sat next to them.
That time you said yes, or no, without much thought.

Only hindsight can provide the necessary context.

Stay awake. Pay attention. But also, don’t fret too much. Don’t be paralyzed. Keep marching. Reflect, OK. Give yourself grace. The small may be bigger than it seems. The big may be more flexible than it feels.

Each decision shapes the story you’ll tell later, but that story is your own.

Big, medium, or small. They’re all chapters in your life.
