Writer’s Block

What do you do when you want to write and nothing will come out?  I’m been sitting here for over an hour staring at the computer, playing solitaire off and on hoping for inspiration to strike me from – somewhere – I don’t know.  Maybe if I knew, then the words and thoughts would start to flow.  There are so many things I want to say but for some reason, no cognitive thought let alone creative thought has come to me. 

It’s enough to make me crazy.  How do I progress and improve as a writer if I can’t get past this huge wall in front of me?
