No matter how determined you are, it's hard not to be influenced

by the people around you. It's not so much that you do whatever a

city expects of you, but that you get discouraged when no one around

you cares about the same things you do.

You'll

probably have to find the city where you feel at home to know what sort of

ambition you have.

The physical world is very high bandwidth, and some of the

ways cities send you messages are quite subtle.
