Making Houston–Johannesburg work
- Houston evenings land in Johannesburg'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.
