Essay wrangling

Whenever I'm writing these things, I get these mental images of me wrestling something incredibly unweildy (say, a crocodile!) and really struggling to subdue it into a cage of logical and linear thought. And I get a great sense of satisfaction to see the crocodile of my topic turned into something nice, and subdued and readable - a nice crocodile skin handbag maybe??

Ok, maybe the metaphor is getting a little bit done.

I'm still writing my introduction, HELP!!
