George Orwell said this quote

I do not think one can assess a writer's motives without knowing something of his early development. His subject matter will be determined by the age he lives in... but before he ever begins to write he will have acquired an emotional attitude from which he will never completely escape. It is his job, no doubt, to discipline his temperament and avoid getting stuck at some immature stage, in some perverse mood; but if he escapes from his early influences altogether, he will have killed his impulse to write.
