After re-story boarding and rewriting my story I have decided to leave it off to the side for a bit. I have been thinking that I am too ambitious in my writing and I need to start smaller. Would it be beneficial for me to write a children's/early adolescent story rather than a science fiction/fantasy story? The idea popped in my head. My brother is autistic and has a fascination with space, science fiction and astronomy. I was thinking of writing a book inspired by him. A young boy who fascinated with the stars and planets unexpectedly meets an ancient astronaut who requests for help. He is teleported to a spaceship and send light years away to help defeat an army of ruthless beasts who want to take over the planet Kepler-62f (need to find a good name). With his knowledge from science fiction movies and books, he must help the ancient astronauts from Kepler defeat the enemy so he can go home. Do you think starting a children's story is a small step in become a published writer?
