One of the challenges I think about is whether I am objective enough with my information and sources. I am constantly asking people, “How are things?” I ask for the same reason I read from different sources. I want to confirm or deny my current affairs assumptions.
One of my strategies is to listen to radio stations from across the nation. With the web, we can listen to stations from all over. So, find a news station from Montana, Austin (TX), or Portland (ME or OR). Listen to what are the local concerns. It really helps put ideas into perspective.
