Hard-block your mornings as "my time" on the shared calendar before the meetings colonise them. I label mine "focus" and defend it like a deadline. Took a while for the team to respect it, but they did.
Moved from Brazil to Portugal and thought the timezone shift would be trivial. Instead my whole team is 4 hours behind and my "evenings" are meetings. How do you protect a normal life when your calendar belongs to another continent?
