Your body lands in a new time zone hours before your mind does. Give big changes a few days to catch up.

Arriving somewhere and being there are separate events with a gap between them. A new job or a new city is complete on paper long before any part of you has adjusted, and the strangeness of the first week is lag rather than a verdict. Adjustment runs on its own clock and does not consult you.

In the first stretch of anything new, resist drawing conclusions about whether it was right. Give it a fixed period, a month or a season, before you allow the question. Keep some small routine from your old life running while the rest of you arrives.
