that's what i'm worried about, that if you don't write the optional essay, it will show that you lack work ethic or something. my academic diversity is not that great either. i suppose some of essays allow you to write about culture or social diversity, but i'd really have to dig deep for that. i like duke's optional essay:"Academic essay — Keeping in mind that we will have your academic transcripts and LSAT score as some evidence of your intellectual aptitude for law school, you should tell us in this essay more about the intellectual contribution you will make in the classroom and outside. You may choose to write about any subject that has engaged you intellectually but this essay should not be a personal narrative. You might, for example, discuss such subjects as a book you have read that had a profound influence on you; an issue in the current public debate; or an individual who has had an impact on your life."how charming!
