I picked the one about always having to write about something original. Well it might sound good and all, but you can;'t always find a lot of information on things like that. I like to play it safe when it comes to research papers and pick a topic that is pretty large meaning you could find a lot of information on it as well as controversial enough that it would be easy to take a post ion. Also if you were to choose to do an original topic make sure it peaks your interest, because if you don;t you'll find yourself bored and most likely not wanting to write about the topic.
