Ray Bradbury said this quote

I believe in having fun first, and along the way, if you teach people, if you influence people, well and good. But I don't want to set out to influence people. I don't want to set out to change the world in any self-conscious way. That way leads to self-destruction; that way, you're pontificating, and that's dangerous and it's boring - you're going to put people right to sleep.
