Just spent an hour on YouTube to check how people are using Claude Code. Kinda surprised how basic most setups are TBH. Any good nerdy channels that go super deep? Not for coding, just for marketing/operations.

Years ago a guy took a train to my city, then walked an hour and a half to my front door. Unannounced.
Bad timing. I had a webinar starting, could only give him 10 minutes. Still feel bad about it.
But here's the thing. If he'd emailed me, I'd have never seen it. My team handled hundreds a day.
He got in because he just showed up.

Bought a Kamado recently. Big ceramic grill I'd wanted for years.
But I knew us. Three small kids, the grill outside and the rest of the cooking inside, someone walking back and forth all evening. We'd probably use it twice and let it collect dust.
So I bought the full outdoor kitchen at the same time. Tap, counter, real prep space. Now there's no reason to step back inside.
Reminder I keep needing. The best result doesn't matter if getting there is too much hassle. People just stop.

Most businesses run ads to get customers.
I run them to buy data too.
Every visitor that doesn't convert is still telling me something. What they clicked, where they bounced, which headline pulled. That's what makes the next round cheaper.
(Claude brainstorms the split tests and runs them now. That one's quietly become a real advantage.)

Ordered a Kamado for the long weekend. Friday morning the shop calls. The delivery company lost it.
It's the size of a small fridge. They lost it. 😅
Next delivery? Wednesday. After the weekend.
So the owner of allesvoorkamado put the showroom one in his car and drove 90 minutes to my house. Friday afternoon.
Made pizza with the kids the next day. I'll never buy a grill anywhere else.

Built a Claude Code setup that can handle basically anything for my marketing. Run ads, edit videos, research, handle customer support, all of it.
But I'm still the bottleneck.
Nothing runs without me kicking it off and checking what came out. The moment I try to let things run themselves, drift creeps in. And it gets ugly fast when skills feed into each other, a small mistake in step one quietly becomes a mess by step four.
Critic agents / scoring etc help. I don't think they're the full answer though.
Been digging through various harnesses (paperclip etc). Trying to figure out what I'm not seeing.
Anyone actually cracked this? So essentially more autonomous marketing :)

Tip: Install Posthog today.
Let it run.
Ask Claude to analyze it a week from now.
(Alternatively, Microsoft Clarity - but I prefer Posthog).

Best feeling of the year so far: coming back from a trip and having nothing urgent to catch up on.
Built it on purpose. Still feels like cheating.

Three filters for anything you're about to publish:
- Is there proof or just promise?
- Would a tired reader finish it?
- Is it in your voice or in AI voice?
Skip any one, the post is weaker than it should be.

Honest thing about GrowOS: there's a learning curve.
If you want plug-and-play, it's not for you. If you want to actually own your marketing operation, it's the best thing I've ever built.

Hired two dev agencies last year. Good ones.
Fired both after one AI developer did more in a day than both of them did in a month.
WHO, not HOW. Pick the person who's 10 steps ahead, not the one who's done 10 projects like yours.

"AI is going to replace marketers" is the wrong sentence.
"AI is going to replace marketers who refuse to use AI" is the honest version. Same with developers, designers, accountants, writers.
Tool or teammate. Your pick.

Wife spent a full day last year building a content calendar. 800 photos, spreadsheet, labels, the whole thing.
I rebuilt the same thing in 10 minutes of prompting. Didn't show her for a week.
AI for non-technical people is the biggest untalked-about shift right now.

The 10-minute-a-day AI people are going to overtake the 10-hour-a-day grinders within a year.
Not because they work less. Because the 10 minutes are better minutes.

Planted 160 strawberry plants by hand a few weeks ago.
Fair reminder that you can be an AI nerd and still want dirt under your fingernails on a Sunday.

The Reversibility x Reach test:
- High reach hard to reverse → always human-reviewed
- High reach easy to reverse → spot check
- Low reach easy to reverse → let it run
Use it to decide what AI does solo vs what you still review.

Two weeks away. Business kept running. Ads, content, support, newsletter.
Every year I come back from a trip a little less needed and a little more surprised by that.

Post organic. Watch what wins over 48 hours. Promote the top 10-20% as ads.
That's the whole pipeline. Everyone wants a secret. The secret is "let the audience pick before you spend."
