In a hundred years there’ll be all new people. What you can affect is the next hundred hours.

Zooming out far enough makes everything weightless, and that is only half useful. In a century the whole cast gets replaced and none of today’s worries survive the swap, which is genuinely calming when you are spinning about something small. It is also no help with what to do tomorrow. The scale you can actually operate at is about four days wide.

Once the big view has done its job and settled you, come back and look at the next hundred hours. Name the two things in that window that are yours to move. Do the first one today and let the century look after itself.
