My dream is to be able to write for a living. I would also love to edit for a living, too.
But when I imagine people actually reading the things I write, I freeze and panic. It doesn't make a whole lot of sense, which is why writing a blog is actually helping me to face more of my fears than just writing novels that no one will be reading any time soon.
It puts more pressure on me to get over that feeling and also makes me a better writer because I must come up with stuff to write without having as much time to edit things. Edits are a security blanket to me, which is why if you ever read a first draft of mine, you'll think it's a bunch of gibberish, even though it makes sense to me.
Every writer should have a blog. =)
