Scary Stuff

Having a children's novel published has been my goal for (ahem) many years. However, when I imagine this dream becoming a reality, I always skirt around the changes it would probably mean to my life. A lot of published authors talk of promoting their work, interviews, talks in schools, newspaper interviews, social networking and book signings. I must admit it all seems a bit frightening, which has made me question whether I'm putting a hundred percent into my writing efforts? Am I afraid of what might happen? I'd like to think that if I ever get that wonderful letter/email/phone call that starts the dream rolling, then I'd take it all in my stride. I hope so, anyway. As a writer, I just want to see my book on the shelves!
Anyone else have the same fears? When I started writing as a teenager, I naively thought that I'd just post off the MS, sit back and wait for the cheques to roll in. Haha. HaHa. Ha.
