Sometimes we must take time to learn what we want before we can go after it. Take some time to do some research, and find something you might want to try, then go for it.
"Read, read, read. Read everything -- trash, classics, good and bad, and see how they do it. Just like a carpenter who works as an apprentice and studies the master. Read! You'll absorb it. Then write. If it's good, you'll find out. If it's not, throw it out of the window." -William Faulkner
