I messed up. I told the doctor I had white collar syndrome, not white coat syndrome.

But maybe that’s a thing too?

If you want to communicate clearly and effectively, read essays.

If you want to increase connection and charisma, listen to music with powerful lyrics.

For the practical and pragmatic:

In business or career…

If you want to read between the lines, study poetry.

If you want to understand nuance, increase empathy, and grasp sonder, read literature.

What a bad pepper costs us On spice, soil, and the slow erosion of what we eat

I thought paprika was just a coloring agent; bland. Turns out: I just never tasted real paprika.

That realization led somewhere bigger: a bad pepper is a symptom of what industrial food has cost us; in flavor, nutrition, & connection to what we eat.

Knowledge from books accumulates not just in your daily memory but also in your subconscious.

These learnings mature in your mind. You’ll have conversations and perform actions that feel second nature, yet you initially have no idea where they came from.

In many ways, AlcarrΓ s parallels what’s happening with AI and the Information Age.

The film is about agriculture and the green tech movement uprooting traditional ways of life. But it feels raw and familiar a few years later, as AI has changed so much.

What a damaged, used book taught me about reading Used books, margins, and footnotesβ€”and why it’s the scribbles that add another dimension

Mass-market paperback books might be disappearing. But used, damaged booksβ€”and the notes they carryβ€”have always been here. And they might be the perfect replacement.

ThriftBooks is such a hit or miss for the β€œacceptable” copies. They should have a lower category called β€œdeplorables.”

I predict AI movies will cause a new effect: the desire for better stories that don't have explosions in every scene. Great writing and dialogue.

One of the reasons I picked up a @mubi subscription because I'm so tired of shallow movies.

Same! Another is its single-use designation so I only focus on the most important thing: writing.

I studied 500 opening lines. Here’s what separates humans from machines. On earning attention through human storytelling

With the age of AI, there’s more content out than ever. That’s why your 1st line matters more today… with nuance.

Before, an opening only had to be a good hook. I studied 500 best selling lines to learn. But it changed.

Now it needs to connect with your soul. open.substack.com/pub/curiouss...

Why e-ink is the only tech that won’t make you sick Platform designs are engineered to hijack your attention. E-ink gives it back.

Today, technology often serves dopamine. Our sleep suffers, as do our mental and physical health. Instead, technology should focus on optimal living. It starts with e-ink.

Surprisingly, it wasn’t AI tools that 10x’d my productivityβ€”it was a digital typewriter.

Using a smart typewriter like the Freewrite helped me get ideas out clearly and completely, without distractions or premature influence from algorithms, feeds, or prompts.

The state of content: where we are now and where we’re going - John Paul Hernandez What is the state of content after AI-generated articles and AI search? It's nothing new. The industry restarted. Learn how to build a modern strategy.

I think content is restarting its market cycle.

AI pushed us back to the early blogging phase: more volume, more noise, less differentiation.

I wrote about why this happens, what comes next, and how brands can adapt if they want real traction.

Why rust isn’t the enemy we think it is How repair, restraint, and time shape what we choose to keep

Rust appears everywhere: playground equipment, grills, screws in outdoor furniture...

Anything exposed long enough will eventually show it.

And yet, when we instinctively fight rust, we often miss what it represents.

Instead, write about why you want to start the project. This gets your thoughts flowing with no pressure and helps you chart your path for research, strategy, and purpose.

In the end, it’s much easier to start. You may even have material from your freewriting.

Writing hack: If you want to write about something that feels too complex or you lack direction, don’t plan or write about it yet.
