Maybe you'll like writing fiction, or history, historical/fiction, non-fiction, Mysteries, biography's, autographies, and other things that I don't know about. 

Hope this helps.

Find a subject you like reading about--say, dragons, gods, etc.--and try writing a small story about that subject. And it may be helpful to try a variey of writing styles to see what works for you.

Sometimes I have trouble with ideas, too. I don't have a particular writing category, but I tried out lots of different ones. I still do random ideas!

Try some of these:

sports--Sometimes one you know nothing about is more fun to write. I wrote a story about a girl who played soccer to boost her self-confidence and I know nothing about soccer.

Historical fiction--Read anything interesting in social studies? I wrote about a slave named Lucy and how she escaped.

pets--Maybe you know a friend who lost a pet and then it turned up. Or do you wish for a pet? Write about what someone has to do to earn money or show responsibility in order to get that pet.

wild animals--You have to know enough about the animal, but then it's fun. My cousin wrote a really awesome story through the eyes of a wolf and I wrote one about a lioness.

celebrations--What if you got a huge suprise gift on Christmas? Have you ever forgotten someone's birthday? Is there a religious celebration you want to write about?

Sci Fi/future based--Imagine life in the future or if a spaceship with you in it landed on a planet. Would the planet be deserted, or inhabited by super smart Martians?

Anyway, I hope this helps. I think sometimes it is easier to write about something you have experienced, like moving or starting in a new school or camp. Happy writing!

My what a lot of great ideas, Hope! Thanks for helping out.
