Moonrat, who is reading everybody's favorite book, Love in the Time of Cholera, pointed out an excellent passage and moral of the story.
Read her entry. I like.
I mean the thing is, ultimately, you should write to write. Write because you have something to say. Because honestly, if you're looking for riches, this is not the way to do it. And if you're looking for fame, it may not come in your lifetime. But if you write because you want to, because you have to, because you can't not write, then what's stopping you? You are not a writer because someone else tells you you are; you are a writer because you are writing.
I am a writer. Whether or not anyone else in this world, in this lifetime, ever recognizes that does not change that fact. Write because you must, because this is how you process the world, and this is the art you want to leave behind. Fickle audiences be damned.
