"There isn't much I'm not willing to learn" is a sentence with a double negative that shouldn't be used when searching for career opportunities. Better said as "I'm willing to learn just about everything" applies more to me, Margaret Medwedew.
I think that labels are limiting but here are some that I might apply to myself: writer, director, stage manager, dramaturg, house manager, literary assistant, costumer, deck crew, board operator, and make-up student. I'm good at what I know and I take time to learn to be better. If I don't know it, I'm willing to try.
If you need someone enthusiastic, efficient, and willing to bring excellence to your organization, I'm the one you should call.
