If you don't have a well-thought out dream, you can start by figuring out where you want to go. If you cannot see yourself fairly or accurately represented in the community you live (from restaurants to department stores to clothing choices to conversations at the dinner table) and nothing there makes you feel awake or alive, I suggest you start doing some research on some other communities.
