Putting the words to paper

"I became a writer shortly after I started putting words on paper..."

I can't remember where I read that recently, but it really struck a nerve.
I am good at putting words on paper. I know that, but the more I try to explore this hobby as a career, the less I find myself putting the words on the paper.

I read websites and blogs about writing and publishing. I participate in online forums about writing. But tonight, as I am sitting here with a blank word document and a cursor taunting me... I find I am struggling. The other stuff is unimportant. I just need to put the words on the paper.
