So you think you want to write a profile? Well, it doesn't matter what you think, because you have to if you want to pass the class. So I'm forcing you to write a profile (there, that sounds better) and you can't find a suitable subject? The first thing I'd do is read this short article about how to think like a literary journalist. The second thing I'd do is start bouncing ideas around in the comment section below this post.
I've already talked to some of you in an informal way about your subject and have been impressed by the quality of the initial ideas. I also recommend looking at what other literary journalism students have written. (Most of those articles weren't written for LJ20, but I know one of Sheena Tahilramani's was.)
