Who do you most admire?
In terms of writing, that is a tough call. I have so many influences. Shakespeare, Chaucer, Poe, Wells, Tolkien, Auel, King, Crichton, and Martin are all favorite authors of mine for various reasons. Each has left a considerable footprint on either my writing or storytelling styles.
Outside of the writing sphere, it would most likely be Mahatma Ghandi.
