What does one do with a case of writer's block, laziness and procrastination?

Or, more to the point, what do you do with a BA in English?

Peanut butter sammie in hand and a cuppa tea in sight, I sit in front of the computer and stare into the void (i.e. screen). This is a habit I'm trying to break; waiting for inspiration, I mean. 

Ideas I have many, it's just that I don't sit down and write. 

The inner-voice-judge stops me every single time, without even giving myself a chance.

So I think it's high time I picked up The Artist's Way again- seriously- and give it a go.
