The second thing you have to do to be a writer is to keep on writing. Don't listen to people who tell you that very few people get published and you won't be one of them. Don't listen to your friend who says you are better that Tolkien and don't have to try any more. Keep writing, keep faith in the idea that you have unique stories to tell, and tell them. I meet far too many people who are going to be writers 'someday.' When they are out of high school, when they've finished college, after the wedding, when the kids are older, after I retire . . . That is such a trap You will never have any more free time than you do right now. So, whether you are 12 or 70, you should sit down today and start being a writer if that is what you want to do. You might have to write on a notebook while your kids are playing on the swings or write in your car on your coffee break. That's okay. I think we've all 'been there, done that.' It all starts with the writing.
