The key question isn't "What fosters creativity?" But why in God's name isn't everyone creative? Where was the human potential lost? How was it crippled? I think therefore a good question might not be why do people create? But why do people not create or innovate? We have got to abandon that sense of amazement in the face of creativity, as if it were a miracle that anybody created anything.
Abraham MaslowThe person in peak-experiences feels himself, more than other times, to be the responsible, active, creating center of his activities and of his perceptions. He feels more like a prime-mover, more self-determined (rather than caused, determined, helpless, dependent, passive, weak, bossed). He feels himself to be his own boss, fully responsible, fully volitional, with more "free-will" than at other times, master of his fate, an agent.
Abraham MaslowA person who makes full use of and exploits his talents, potentialities, and capacities. Such a person seems to be fulfilling himself and doing the best he is capable of doing. The self-actualized person must find in his life those qualities that make his living rich and rewarding. He must find meaningfulness, self-sufficiency, effortlessness, playfulness, richness, simplicity, completion, necessity, perfection, individuality, beauty, and truth.
