I hate cover letters. Almost as much as I hated classifieds when I was searching for work in the real world -- I wanted to place my own ad touting my features and benefits, and encourage prospective employers to send me their offers so I could consider who would deserve my talents. Ok, a little on the ego-driven side I admit, but the traditional resume seemed such a weak way to present who I am and what I could bring to a company.
So now I'm composing cover letters and fighting my creative urges again... I may gather quotes from my students: "He's my favorite coach." "He's funny!" "He ties my shoes."
