Sample

Real output from a made-up example

Made by the same code as the tool

Two short posts by a made-up writer, measured the same way your writing would be:

Most of my week is meetings I didn't ask for. So on Fridays I close the calendar and build the thing I've been putting off. Last Friday it was the onboarding email. It took two hours and it's the best thing I shipped all month. That's the whole trick. Protect one afternoon. Use it for the work only you can do.
