> The most lasting and effective way to change your life is to change who you’re surrounded by. Since networks so powerfully shape who we are and what we do, the best way to change ourselves is to change our networks.

That's why it's good to be part of groups when you move to a new town, groups that probably will have person with many similarities with you (and not the only one that made you choose them). Be part of a literature group and you'll have things in common that go beyond reading books, as being part of that group will have effect in your time, routes you take within the city, places you'll eat, stores that you'll go, and so on.
