Procrastination

My friend once told me that procrastination is a lot like masturbation; it's good while it lasts but in the end you realise you've just fucked yourself. I'm supposed to be doing my English essay which is due in tomorrow. I've done the introduction and now I've totally blanked. Why can't my mind stop thinking about everything at once? It's leaving me no room to concentrate. Man, I need some motivation. On top of it all I'm hungry. So in other words, I'm fucked.
