writer
A good writer is someone who makes you realize something you already knew, even though you didn't know you knew it.
When I typed out that sentence, I left out the word "good". I didn't mean to, but when I read back, it wasn't there. It just said, "A writer is someone who makes you realize something you already knew, even though you didn't know you knew it."
And I think it's true, maybe. Everyone writes, even if it's only just a little, even if they wouldn't say they do. Even if it's just typing text messages now and then. But you become a writer when you write something that someone reads and thinks, wow.
Even if that someone is only you.
Is there a distinction between "writer" and "good writer"? Every writer has bad days, it's never all "good". And what does "good" mean, anyway?
If you know you're a writer, if you feel it, I think that's enough.
