Question--Does a Compulsion Make Me a Writer?

I write a lot on several different websites and not. Does that make me a writer? I always thought I would have to get paid a lot of money and travel in elite circles to be a "real" writer. Does volume count? I turn out a lot of words, but are they words that count? Do they inspire? Or explain? Are they significant? I wonder if Emily Dickinson considered herself a poet. She published very few poems during her lifetime, but she wrote volumes. I and I think the world of literature consider her a poet of dramatic and exalted stature. Does my ramdom ramblings constitute me a writer? Maybe that is left to posterity. All I can do is write it.
