Making Seattle–London work

  • Seattle evenings land in London's late night or early morning, so protect one window and treat it as your appointment.
  • Trade a voice note when one of you wakes up. It is waiting for the other at the end of their day.
  • Keep a shared list of things to tell each other, so the call is not spent catching up on logistics.
