Okay, I really actually want to write a book and be an author but I don't know what kind of book?

The best stories are about something the author experienced and then embellished on.

Write a very detailed story about something that happened to you. Lets say a family camping trip. When the story is done, start changing things. When everyone woke up in the morning, your little brother was gone. No sign of violence. What do you do next, call the forest range and police and search the woods. Then go through all the steps you would to find your brother or his kidnapper.

Then give it a surprise ending. Police arrest child kidnapper who was camped nearby and had your brothers clothes, and send him to prison. A couple of years later, your family is camping a few miles from where your brother disappeared and you go for a walk. While alone in the woods, you see a young boy, dirty with long hair, run through the forest and disappear into the brush.

Think about genres you like to read or watch. If you're into sci-fi, read some science journals and think about how some of that technology could affect the future. Take a stereotype and turn it on its head. Maybe the princess didn't want to be saved from the dragon by the knight. Look at people and think about what makes them tick, what they would sacrifice for something, what their worst fears are, how they would react in certain scenarios. Look at a story and think about the what if's. Try to remember your dreams. Maybe even Google "writing prompts [whatever genre you're interested in]". Think about what kind of story you would want to read. Most of all, read.

Don't dismiss any ideas you get, no matter how ridiculous. Sometimes those end up being the best ones.

Try starting small rather than jumping straight into the deep end. Maybe try your hand at a couple of short stories before you think about writing a book. And remember, the first, second, third, etc. book you write doesn't have to be amazing. You'll get better the more you write so keep writing!

Please not that you are only 13, and writing takes a lot of practice. As a teenager, you have more time in your life now than you ever will in the future, so what you do is write another book. And another. Let people read them, get feedback, but don't take it too seriously -- they are your books.

There's a saying that you need to spend 10,000 hours to master something, and another saying about needing to write a million words before you start producing anything that's beyond crap.

You know how to put together a nice, concise question with just the right amount of important details. I predict you'll go far if you apply yourself to the practice.

Hi! I started writing when I was 12, and a book I wrote when I was 13 almost got published. I think it's best if you go with some kind of fantasy or science fiction--that way you can make up enough of the world to bring it to life without showing how young you are. Good luck!

You may begin by reading good books and studying how they are constructed. Concentrate on Character, Plot, Dialogue, Pacing and so forth. There are also many websites such as http://silvablu.skeeter63.org/HMG/00-Introduction.... which can assist you.
