How to develop interest in research
Relate the topic to yourself.
The easiest way to develop an interest in research is to look into something that affects you personally, or that will affect your life or one of your interests in some important way. If you're interested in the topic you're researching, you'll enjoy reading and learning about it.
If you're writing a research paper for a class, your professor may have given you a broad topic. Your project can be any smaller thing within that topic, so try to find something that affects you personally.
