Confused.

I have decided that blogs are a lot of pressure. Do you write it like an email? An email to your friend? Your Grandma? A stranger? Or is it like a journal? A conversation? An interview? I am still trying to figure this out. I had thought that I wanted to work on my writing -- but then you can´t work on it whilst having it as a showcase! At least I can´t. One of my goals in life is to take a creative writing class, but I don´t think I am there yet. I think it will just have to be whatever comes out. That seems to be my style in life anyway. Email style, if you will.
