Bradbury's motivation to write was driven by his imagination. As a child, Bradbury was an avid reader, devouring works by Wolfe and Hemingway. This helped to drive his fascination towards the arts. At the same time, Bradbury felt an instant attraction to the genre of Science Fiction writing. He was able to emulate the writing of science fiction style of Jules Verne. Bradbury felt an instant connection to writing in a science fiction style, as Verne did: "He believes the human being is in a strange situation in a very strange world, and he believes that we can triumph by behaving morally." This desire to construct a reality of what can be out of what is helped to provide a basis for why Bradbury wrote.
It is here where another rationale behind Bradbury writing is evident. Bradbury was sincerely excited by the pursuit of ideas. For Bradbury, the intellectual engagement with ideas through literature fueled his work and provides a rationale for his writing:
Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.
This becomes the basis as to why Bradbury wanted to write and saw writing as a way to communicate his beliefs on the importance of ideas. It is this particular end that drove Bradbury's writings and provided the desire for him to enter the domain.
