One of the main things I have learned from moving overseas is the power of expectations. Nearly always, our disappointments and frustrations result from failed expectations. C.S. Lewis wrote:
Imagine a set of people all living in the same building. Half of them think it is a hotel, the other half think it is a prison. Those who think it a hotel might regard it as quite intolerable, and those who thought it was a prison might decide that it was really surprisingly comfortable.
from God in the Dock, p. 52
