Tread softly upon the earth because the faces of the unborn look up at you.

Literary science fiction is a very, very narrow band of the publishing business. I love science fiction in more of a pop-culture sense. And by the way, the line between science fiction and reality has blurred a lot in my life doing deep ocean expeditions and working on actual space projects and so on. So I tend to be more fascinated by the reality of the science-fiction world in which we live.

Old Rose: It's been 84 years, and I can still smell the fresh paint. The china had never been used. The sheets had never been slept in. Titanic was called the Ship of Dreams, and it was. It really was.

You don't rest well as long as you're seeking vengeance. I feel sad justice wasn't done, but it's time to move on and sleep well.

Nature's not our enemy, it's our sustenance; and we need it - and we need nature healthy for us to be healthy and to survive long term

Rose: You're crazy. Jack: That's what everybody says but, with all due respect, Miss, I'm not the one hanging off the back of a ship here. Come on. C'mon, give me your hand. You don't want to do this.

So my message is in whichever realm, be it going into space or going into the deep sea, you have to balance the yin and yang of caution and boldness, risk aversion and risk taking, fear and fearlessness. No great accomplishment takes place, whether it be a movie or a deep ocean expedition, or a space mission, without a kind of dynamic equipoise between the two. Luck is not a factor. Hope is not a strategy. Fear is not an option.
