Day 28: Make it reusable, then show it.
Two moves to close the week: turn your proudest build into something you reuse forever, then show one piece of it to the world.
Welcome to Day 28 of the challenge.
You’ve built a lot this month. But most of it you’ve built once. Today you do two things: you turn your proudest build into something you keep and reuse, and then you show one piece of it to the world.
Keep it, then show it. That’s the whole day.
A word before we start
The difference between doing a thing once and owning a skill is whether you can do it again in seconds. A one-off is a nice afternoon. A reusable skill pays you back every time you reach for it. So before we show the world anything, we make one thing permanent.
And the showing isn’t a humblebrag. It’s proof. In a conversation drowning in theory, a real person holding up a real thing they made is the rarest thing in the room. That’s not vanity. It’s the correction.
Step by step
Step 1.
Pick your proudest build. The scorecard. The morning brief. The money model. The industry review. The one that made you sit back and think, I made that.
Step 2.
Open Cowork in your desktop app, pointed at your Switched-On folder. Opus for this one.
Step 3.
Make it reusable. Turn the one-off into a skill you can run again in seconds.
Take [the thing I built]. Turn it into a reusable skill in my Switched-On folder: a clear saved prompt or template, with instructions, so I can produce a fresh one in seconds whenever I need it. Then tell me the one line I type to run it.
Step 4.
Test it. Run it once from the saved version, on something new. If it works the second time without you rebuilding it, you don’t have a one-off any more. You have a skill.
Step 5.
Show one piece of it. Screenshot the result. Write one true line in your voice, not “AI is amazing”.
Something that actually happened: what it changed, what surprised you, the thing you’d been avoiding that took an afternoon.
Want it sharper? Paste your line to Claude and ask it to sharpen, not rewrite.
Editor mode, exactly like Day 16.
Then post it, and tag #SwitchedOn so I can find you and cheer you on.
If public feels too big today, send it to one person.
Step 6.
Lock it in.
Add to MEMORY.md: Day 28, turned [the build] into a reusable skill. The one line to run it is [line]. And I showed one piece of it to the world.
A safety note
Blur anything private before you post. Numbers, client names, anything from your money model or inbox.
And keep the line: the words on anything public are yours, not the AI’s. Share it at 80 percent, not at some impossible 100. Done and shared beats polished and never.
What you’ll notice
Two things. The quiet power of “I can do that again in seconds now”, which is a different feeling from “I made a nice thing once”. And the replies when you show it: “how did you do that”, “I’ve been meaning to try this for months”. You stop being someone quietly using AI and become the person other people ask.
Why this works
A one-off impresses you for an afternoon. A reusable skill changes how you work for good. And showing it turns a private skill into visible proof, which is the most persuasive marketing there is, because it doesn’t feel like marketing. It’s just true.
Key takeaway
You didn’t just make things this month. You can remake them, on demand. That’s the difference between a good month and a permanent upgrade. Today you made one of them permanent, and let the world see it.
Where this is heading
Tomorrow, the big one. You hand the whole system one real problem from your actual work, and watch what becomes possible now that it knows you.
Tomorrow on Switched On
Day 29: Give it a real problem. Watch the whole thing work.
One real, messy problem from your business, handed to everything you’ve built. The payoff of a month of context.
