Read liberal and conservative news sources; business, history, religion. All of this creates a renaissance persona that can stand toe-to-toe with any Fortune 500 executive. Get a nice suit and wear it; don't see yourself as a blown-in hayseed. View yourself as a modern Jeffersonian intellectual agrarian. What's on your bookshelf? How many hours a week do you read? Readers are leaders. Cultivate friendships across disciplines, politics, and religion. Entertain guests often; that's a cheap way to receive cosmopolitan information without having to travel.
