where the writers are

I am stuck today. I tried to start writing this morning, but my mind feels silent. I know there are a million things I want to say, but nothing is coming onto the screen. Maybe it's because I usually write by hand. The computer kind of slows me down sometimes, and makes me nostalgic for simple pen and paper. I am envious of people I see writing and being able to write in any format.. how can I do that?
