It's hard work making movies. It's like being a doctor: you work long hours, very hard hours, and it's emotional, tense work. If you don't really love it, then it ain't worth it.
George LucasIf you want to be successful in a particular field or endeavor, I think perseverance is one of the key qualities. It's very important that you find something that you care about, that you have a deep passion for, because you're going to have to devote a lot of your life to it.
George Lucas
