Always listen to your heart and you will get the right answer. Be calm and relax, hold a pen and paper and jot down whatever comes in mind, just simply write those ideas without dawdle. While writing, do not erase any idea which you have noted down and don’t even edit it. You can edit it later when you evaluate the list of your ideas.
Once all the ideas are in place, it is time to assess each one of them. Do a quick research on each of the ideas, so you can know whether it has sufficient data on it so you can produce a lengthy yet attractive research paper. There are lots of places you can go to carry out the research like visiting the library of your college or researching the idea on the internet, just choose which one you feel suitable. It is also highly possible that while researching any idea, you might come across a more suitable or interesting one. Go through books, journals and knowledge based web pages.
Another thing you can count on is your experience during the whole academic year. Take another look at the topic you have chosen and see if it is relevant to any major subject of your course, any of your hobbies or favorite activities or any other interest. Also include your own perspective about the topic and what you personally think. Mostly the college instructors take great liking to such research papers in which students show their own creativity and opinion.
