Research Questions and Topic Refinement

I wasn't able to make it when we went over this topic, but I will go off of my own knowledge.  For me it is very hard to decide a topic, because it has to be a good one that you and others have interest in, or you won't be able to write a whole paper.  So an effective way to choose a topic is to do something you have interest in, and ask others if they have interest as well.  But first you should write down all the different topics you have interest in, then ask people about each of them and use the process of elimination.  I still have only a vague idea of what I want to do. This causes me too much stress.
