Making San Francisco–Singapore work
- At 15 hours apart, one of you is asleep for most of the other's day. Agree who flexes on which days, so the late calls are shared.
- Lean on asynchronous rituals: a daily question you both answer, photos of your day, a letter you each add to.
- Plan one long weekend call a week, when nobody has work in the morning.
