The way I write a twice-weekly newsletter with 300,000+ readers:

I block off the whole day on Monday and Thursday. Get the kids to school, go on a walk with Meg, then head straight to the studio and write. Once I have a draft, I take a shower, eat a little lunch, and go back and re-read the draft and edit the thing. Then I send it to Meg for a big edit. I make changes based on her feedback, then schedule it to post the next morning.

To quote Andy Warhol, “It’s work!”
