So I know some people, who like to make up stories in their head and they just keep adding to it, and that's fine.

That's your decision.

Sometimes I think it's better because a lot of the time when your writing, you can't think of a word or words to describe something.

For me, it's when it comes to fight sences.

I hate having to write them out because sometimes, I don't know how to describe it.

So sometimes it is better to just think it in your head.
