Writer's block cure?

I am so sick of writing cover letters. Sure, being unemployed means I can take video game breaks whenever I want (and I often have), but if I actually want a job I have to step away from the Playstation and get my nose back onto the grindstone (not nearly as fun).

Here's a little website called "Written? Kitten!" that rewards you for writing by giving you a picture of a kitten. Motivation: regained. ;)

(My first photo! So cute.)

What are your favorite self-motivation tricks and tactics?
