How much important for a person to go out in the world and explore new placesMany a time it is necessary for a person to get out of the comfort zone and see the world for what it actually is. Rather than living in a single place and seeing the same people and same kind of things daily which does not let him/her grow even if there is growing knowledge remains confined.
Often there are people who have never stepped outside their villages, cities and states but have a varying opinion about the other places as if they know it all. Especially the people of small-town have a particular kind of opinion for big cities and people of big cities have for small town and unless they exchange places they can't really understand pros and cons.
Similar to the way James Mill wrote "History of India" without ever coming to India and even classified it into three parts. Until and Unless you go out to a particular place all you have are biases.
