If you want to be successful in a particular field of endeavor, I think perseverance is one of the key qualities.

Good luck has its storms.

None of the films I've done was designed for a mass audience, except for 'Indiana Jones.' Nobody in their right mind thought 'American Graffiti' or 'Star Wars' would work.

I'm not much of a math and science guy. I spent most of my time in school daydreaming and managed to turn it into a living. When I was making "Star Wars," I wasn't restrained by any kind of science. I simply said, "I'm going to create a world that's fun and interesting, makes sense, and seems to have a reality to it."

Heroes come in all sizes, and you don't have to be a giant hero. You can be a very small hero. It's just as important to understand that accepting self-responsibi lity for the things you do, having good manners, caring about other people-these are heroic acts. Everybody has the choice of being a hero or not being a hero every day of their lives.

You have to have a thick enough skin to cope with the criticism. I'm very self-critical and I have a lot of friends that I trust who are film directors and writers and people in my profession.

I grew up in the era, 'Don't trust anybody over 30.' And, you know, I still feel that. Don't trust me.
