Writer's Block

Writing can be a real pain in the ass sometimes. I get into these modes where I’m capable of writing anything because as soon as I type the words I doubt them. Is this the best way to say this? Is this even interesting? Who would want to read this? It’s utterly self defeating. That is what writer’s block is to me. It’s not a lack of ideas but a lack of faith in those ideas and my own ability to express them.
