It happens

It does.
Writers, we don't always get to choose what to write about. We read, and we know what is in us. The stories that are ready to be told, in whatever form, work their way to the front of the line. We may sit down to share one thing, but what comes out is what is ready.
The important thing is to write at least a little each day.
It may be absolutely nothing of importance, etc. It may simply be the dumping of the day's thoughts, feelings, struggles. That is OK.
It has to happen.
The gutters and drains have to be kept clear and open.
You must continue to allow your voice to practice.
And every now and again, you are given the opportunity to bring something beautiful, or terrible in it's impact, into life.
That is what a writer is.

It's different from being an author. One can be an author without being a writer...they can be someone who writes.

You know the difference.

Many observers do not. There's no malice here. Every writer is an author. But there's an immense difference between Steinbeck, for example, and Dick Francis. Danielle Steele and Madeleine L'Engle. Stephanie Meyer and Jane Austen. Look at those and tell me what the differences are. Look at those and tell me who saw greater income? Who was motivated by what? I'm not discounting anything, or anyone's talent and ability.

I'm defining. Marking the difference.
Do writer's have disdain for money, fur advances? Are they about the "suffering for my art?"
No. Writer's need to eat, and they'd love to live doing what they are.
That's not the difference.
Look again. Focus. Think.
Be honest.
So.
Write.
Write the fluff, the bs, the empty. We all need to do it, to read it even.
Then write the truth.
The history.
The humor.
The beauty.
Wreck us with your words, the pictures, the emotions...and let us find our truths, our history, our beauty...ourselves...in them.
But above all else,
Write.
