What does Jason Aldean's song church pew or bar stool mean?

The song is narrated by a person who lives in a small town with two types of people: those who chase fulfillment through religion and those who chase fulfillment through alcohol. The narrator feels alienated because he wants more than to seek fulfillment through either of these options. The narrator concludes that he must leave his small town if he is to achieve his big dreams, which are not understood by those around him.
