Research topic too hard?

Some the other day when we were asked to share our research topic I wasn’t prepared.  I actually didn’t pick a topic until that moment when Ms. Fletcher called on me to share.  I chose a topic I thought I would want to write about but when I started doing my research I found it somewhat difficult to find articles that made enough sense to make a favorably argument.  I was getting frustrated and I finally decide maybe the best thing to do was to pick another topic, so I began my search.  I started asking my brother because I recalled he had to do something like this.  He told me the best thing to do was to keep my original idea but change it up a bit.  So my advice to those who are having difficulty would be the same my brother gave to me, change it up a bit.  Keep your concept but change your wording.  If you still are facing difficulty then maybe it will be best to find other less difficult topic.  Ask your siblings or another people for some suggestions.  Some of them might have the one you’re truly interested in.
