1. Write about topics that interest you.
2. Write about topics that are relevant to your audience.
3. Write about topics that are interesting or controversial.
4. Write about topics that are unique to your audience.
5. Write about topics that will make your readers think.

7. Write about topics that will make them cry (or at least feel something).
