I'm so boring I wear white underwear almost all the time, and I'll tell you now that I like cheezy monster movies. There's no way my life could stand up to the attention of being famous. However, I'd like it if my books were well known and if they sold a gazillion copies each. No, I don't know any famous writers, although I do know many wonderful writers. Much less than you'd think.
Most writers have other jobs.
That means I need to sell five books just to rent one cheezy video. No, there's not much call for picture books of stick figures. For the most part, publishers like to keep writers and illustrators separate. Fortunately all my illustrators have been great. Only someone who has not tried to read my handwriting could ask this.
