I agree with both posters. One more aspect of this to think about has to do with the inverse position of the question--what a citizen should NOT do to help his country progress. Sometimes that's not just the opposite of what one should do. So what things (attributes, actions, attitudes) would impede or hinder or slow down progress? I would guess your list would contain things like being unwilling to work (expecting others to provide for them), demonstrating apathy (not participating in the rights, responsibilities, and privileges of being a citizen), or even acting against the best interests of the country (as in treasonous behaviors and supporting those who are considered "enemies" of the country). You get to the same place, of course, but it's another perspective on the issues that matter most. Sixty words?! Good luck with that!
It's not clear what kind of progress you mean - social progress? Personal progress? National? I'll assume you mean social. The previous post is right in that 60 words is hardly going to do it. But since you have a focused assignment that requires it, you'll want to choose your topics wisely.
I would focus on the following:
1) Service - giving back to the community or the country in a tangible way, at no charge
2) Activism - not only voting, but holding elected officials accountable, and reminding them when they go astray or need to make a change for a cause or issue
3) Education - That is, pursue your own so you can be informed, and educate your children and your community, so that they can follow your example.
I am not sure that anyone would or should write it for you. I think that it's going to be a challenge for you to summarize the responsibilities of citizenship in 60 words. Instead of answering this, I would flip it back on to you in suggesting what you think comprises a proper citizen? In your mind, what do you think a good citizen should do? How do they behave? What is their relationship to their government and their fellow citizens? What are some of the requirements, or elements that should not be avoided, that have to be fulfilled in order to be a proper citizen of a country? I think that you would probably be referring to a citizen of a democratic country, so this might be where your thinking can begin. What does a democracy need to have in its citizens? (To be honest, if you had another form of government that is so centered on government and power brokering, the "proper citizen" definition moves more towards strict obedience.) Why does democracy need requirements of its citizens? What are some of the dangers of citizens who do not fulfill or violate their responsibilities? These are some of the questions that you might want to ponder as you compose your response. In the end, this one is so open ended. Even if I were to answer it, you could have ten editors in an hour respond ten different ways. It will actually be more work for you to sort through everyone's different answers, which proves why it might be better for you to take what people say, generate your own answers and thoughts, and compose your own writing on this one.
