Cultivating contacts outside your social circle brings a little ordered chaos into your life. Most of us find the idea of chaos stressful, but history suggests that the disorder following upheaval often brings unexpected benefits: The Plague, for example, helped usher in the Renaissance. Fortunately, you don't have to wait for catastrophe to strike; just form relationships with all kinds of individuals. I call them "unusual suspects," because they'll naturally push your thinking in new directions. Ask yourself which groups have made you a bit uncomfortable in the past, and try reaching out to them. (I'm from Israel, and one of my unusual suspects runs a church.) Make a point of getting together with your new connections with no agenda. Even if you just chat, you've created an opportunity for ideas to be born.
