Did you read the article?, is about doing the importnat stuff when no one is around to distract you. >Not an early riser? No problem, just flip it.

Avoid the day. And when it’s done, that’s when your focussed work starts (my favourite adherent of this approach is Demis Hassabis: who works a “second day” from between 11pm and 4am).

I read the article and had the same response as GP. I don't know on what basis the author believes you can "flip it", but it seems at odds with the idea that at some point your day is "poisoned" and the rest must be written off, presumably until you can reset it by sleeping.

How do you flip it though? What does that really mean?

I find that advice vague. What does "avoiding the day" even mean?

Anyway, for me it was easier to wake up earlier than try to do focused work after an exhausting day with children. Doing stuff in the middle of the night is a privilege of the childless anyway.

This is not possible to do in most workplaces, unless it's remote and the time zone difference works in your favour.
