Have you written all four already? What happens if you write 3, then for the last one you have absolute writers block, or you end up writing stuff you are totally dissatisfied with?
I haven't written all four yet, but I do have outlines of the ideas. I collect ideas/research/examples for a long time -- often years -- so when I go to write a post, I can sort through tons of stuff. That helps with writer's block.
