Wanting to Write vs. Actually Writing

I've been thinking about writing poems a lot lately, but have not actually written anything.  I've listened to a lot of poetry on podcasts, but have not written anything.  Sometimes it takes a lot to sit down and clear the noise inside my head and around me and to just write.  I let the busyness of life push me around, to bully me around so I do what it wants to do and not what I want to do.  Why is that?  Why can't I just do it?  What's holding me back?  Is it fear?  I want to write, but I don't do it.  Usually when I sit down to write I can do it.  It's not like I'm sitting there in front of blank sheet and not being able to produce like most writer's block.  It is more of block of even sitting down to put pen to paper or fingers to keyboard. 

Jesus, help me to write and sit down and move past the imaginary wall that is stopping me from writing.  Help to just do it!
