If you can do what you do best and be happy, you're further along in life than most people.

You have to enjoy life in the process. It may sound corny, but it's true. At the end of the day, we can't always achieve everything that we dream of but you do have to enjoy life in the process.

I've never known a situation in my career where a terrible script turned into a movie that was out of this world or was a success.

It was invaluable to have a dear friend who you have known for over a decade, be a partner in a film like Titanic.

I got everything I need right here with me. I got air in my lungs, a few blank sheets of paper. I mean, I love waking up in the morning not knowing what's gonna happen or, who I'm gonna meet, where I'm gonna wind up. Just the other night I was sleeping under a bridge and now here I am on the grandest ship in the world having champagne with you fine people. I figure life's a gift and I don't intend on wasting it. You don't know what hand you're gonna get dealt next. You learn to take life as it comes at you... to make each day count.

Climate change is severely impacting the health of our planet and all of its inhabitants, and we must transition to a clean energy economy that does not rely on fossil fuels.
