Check out this quote from a famous novel:
"There is no use trying," said Alice, "I cannot believe impossible things."
"I dare say you haven't had much practice," said the Queen. "When I was your age, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast."
One of the secrets to creativity is seeing like a child sees--i.e. approaching each moment with naivety, "discovering" everything you come across before you question it, and throwing your whole being into believing things; believing that Santa Claus makes an annual journey, for example, or that your mother has X-ray vision, or that if you practice enough you'll be able to fly.
Or that when you grow up you can be a writer.
Lewis Carroll knew his stuff.
