Quite possibly the best quote ever, on so many levels.
The question, "Am I a writer?" is irrelevant. The real question is, do you want to write?
Writers write. You get up every morning and hit that keyboard. You get the words down and build stories. You might have to do other things to keep groceries in the pantry, but above and beyond everything else, you write. Every day. Despite all the disappointments, despite all the obstacles, you write.
As you write, you learn. You create characters and give them problems and make them work to solve their problems. You send your stories out to market and keep sending them until somebody starts to publish them. But the stark fact is that no one can know if you're a writer - you won't know it yourself - until you have written well enough to be published.
Frankly, most people give up. Writing is hard, lonely work and they get tired of it. But every successful writer starts exactly where you are now, and succeeds by writing and writing and writing until they get published regularly.
Do the work. Write. Learn. Write every day. Read and learn from published writers. Work at it every day. There's no other way to become a writer.
