I grew up reading a lot of fantasy/sci-fi. It was really all I read - anything from 'Dragonlance,' when I was 12, to 'The Wheel of Time' and Robert Jordan stuff, to George R.R. Martin, who did 'Game of Thrones.'
Really, acting is like anything else. The more time you put in, the more you learn and the more you can give back to the industry.
