Don't be afraid to express your own opinions and feelings. You are a vital part of the subject. No matter what the topic, you are really writing about how you understand it, how you feel about it. Good writing has personality. Readers enjoy sensing a mind at work, hearing a clear voice, responding to an unusual sensibility. If you have chosen a topic that is of general concern, and if genuine feeling and intelligence come through, you will be interesting. Interest lies not so much in a topic as in what a writer has made of it.
