I believe it is important to speak to your readers in person... to enable people to have a whole picture of me; I have to both write and speak. I view my role as writer and also as oral communicator.
When I'm reading material, if I'm a little bit afraid of a part and I'm willing to admit that to myself, then I'll do it, definitely. If I'm worried about being able to do it, to get it - I absolutely just love it.
