Solar Lottery (I think this was Dick's first full-length novel) clearly shows Dick is learning the craft in moving from SF short story writer to novelist. If anyone has read any of the interview type
books, Dick was really not making anything close to a livable income off of SF writing and felt pressured to crank out stories at a prolific rate (one of Dick's colleagues supposed that the stress of producing at anything close to producing a livable income was one of the major factors in Dick's early death).
