Writer's block

It's really bothering me that I can't seem to break this. I want to work on my novel and I want to work on my memoir. But I can't seem to get going on it. I open up the chapters, maybe write a couple of sentences, and then stare at it for a while before I finally get so annoyed I close the window. I need to get working. You can't get your dreams if you don't do the work for it.
