Sorry, I didn't mean to make things about me.
My point is, that we shouldn't agonize about whether we are a "real" writer or a "real" author. That should be quite obvious. If you write on a regular basis (as opposed to just talking about the book you are going to write) then you are a writer. You may not be good, you might never be good, you might never get published ... that's a whole different series of self-doubts and insecurities. You're doing it, and you should give yourself credit for that. If you have completed something you are an author. The same applies. No matter how good you are, or will be, or how successful you may become, you have authored a book or story, so give yourself credit for that.
What you then have to ask yourself is do you have the tremendous desire and the commitment it will take to become the best writer that you can be (all the while knowing that success might never come). Maybe you don't have that level of desire and commitment. That's OK. Go find something else you can be passionate about. Sometimes, in order to earn a living we have to slog away at things we don't want to do, or at some dead-end job that puts food on the table. But what we don't have to do is be writers, not if writing is something we dread to do, or even something that bores us. And there are people who post here from time to time who say they want to write but they hate the process. (Obviously they like making up stories. That's the first step, but that's not all.) If that is the case, do something else. The world is full of wonderful things to do.
If you have the desire and the dedication, you will improve. Whether you will improve enough ... well, that could take a long time to find out. For most people when they are in the early stages of learning to write, and sometimes even later, their first and second drafts are pretty dire. Learning may come in small, small, small, steps, with only occasional epiphanies that shoot you ahead a fair distance. But for all the grinding away, and the frustrations, and the isolation, underneath all that you have to enjoy it. Because otherwise, why do it, when the joy you get from doing it may be the only reward you ever get?
But it needs to be important to you. You need to take it seriously. You need to care about all the aspects and not say, "The story is all that matters." A compelling story is vital, but there is no one thing that is "all that matters." You need to care about it all. Certainly you should play to your strengths, be willing to take a few chances, but you should not ignore the rest or feel that just by breaking the rules you have done something brave and fine. Usually (not always, but most of the time) when someone thinks they have done something startlingly original, when they think they are about to re-create the genre, all it means is that they don't read enough, they don't know what is already out there. What they have done is throw away one or two genre conventions and managed to include just about every single one of the others. What they have done is what 99.99% of the other new writers who want to be original have done.
Sometimes, though, someone does come up with something amazing and original. But originality comes from reading widely, from gathering a vast variety of influences in and out of the genre (if you only read a few books you will be overly-influenced by them), and then -- the most important thing -- how you put all the pieces together.
When it comes down to it, how you put the pieces together is always the most important thing. You can learn all the rules, you can follow them slavishly (or break them all), but in the end it comes down to how you put it all altogether, and that is where inspiration and talent come in.
After that it is persistence, persistence, persistence and timing. With persistence, you increase the chances that you will someday have the right timing, that you will have the right book at the right time for at least a modest success. You increase the chances enormously. But persistence comes from desire, from that compulsion that tells you that you have to write, that you won't be happy unless you write, and a compulsion to share what you write with others, to communicate your stories, your visions, to as many people as possible.
All the people who say, "I write for myself but if anything I write happens to be published ..." it is never going to happen. There is nothing wrong with writing for yourself. Therapy, hobby, whatever, why not? But your work is never going to "happen" to be published. You have to work toward it for it to happen, you have to take your aspirations and your writing seriously, and not innoculate yourself against disappointment with "if it happens."
Feel a passion for what you do, remember that all of it matters, love words and making up stories, be prepared to work hard, and TAKE IT SERIOUSLY.* And if any of that means you are being "precious" about your writing, then so be it. It's better than not caring enough.
