Classic writer

I feel I have something to say. I also feel I have nothing to say.
I know it doesn't matter what others think of my writing. I do worry what others will think of it.
I know if I start writing something will surely come out of me. I also fear nothing may come out of me.
I tell myself I should write -- now! I also keep myself busy with mundane stuff to avoid writing now.
I tell myself to write with no specific purpose. I also question myself why I lack a purpose.
I think I am a writer. I ask myself what makes me think I am a writer.
