How can people demonstrate their understanding of the responsibilities, duties and obligations of citizenship?

There are lots of ways in which people or individuals will be able to show their understanding of the obligations, duties, and responsibilities as citizen of a certain land. One of which is through following the laws and other rules that have been implemented by the government of the land. 

In this way, one will be able to live harmoniously with others. In order to further do that, one should understand the things that needs to be done by an individual depending on the role that is being played. Example, policemen helps keep peace, teachers give guidance and imparts knowledge to students, merchants trade, doctors aid in healing diseases, presidents rule and look out for the wellbeing of all.
