what you can do, and this might sound kinda odd at first, but for practice, it might help. i did this in my english class when i had no clue what to write. just sit down and write something, regardless of whether or not it pertains to the question. eventually something worthwhile will come out. and then you can pick out what the good idea was. and when i say anything, i mean literally anything. example:
"This is really stupid. i don't want to do this. blah blah. My dog barks too loud. Sammy's hair sticks up funny. what's up with spongebob? how does a pineapple actually work as a house?....... (Brilliant idea) my nose itches. i need to do dishes. Becky
and then you realize you had a brilliant idea and you can now write your essay. and with practice, the brilliant idea should come sooner and sooner, so you won't have to spend as long on the pen diarrea. it worked for me in my english class, because i often had no clue just how to begin, and getting that first line down was the hard part, but when you're not so concerned with it, it comes out easier, assuming of course you have some vague idea of what the question means and just don't know what to put down.
