Asking why

We are all presented with various systems. When we are born, we have a particular social setup, a particular educational system, a particular type of Government functioning and so on. Many of us integrate ourselves into these systems and get satisfied with it. We have to be a part of all these but we also need to question them.
Asking the question why is a sign of thinking. Instead of accepting whatever that is presented to us, we can try to reason as to why a particular system has to work in the way it is working. Asking why also leads to newer and more creative alternatives. It helps us to discover further possibilities and change things if necessary.
