"And, hey, I'm not under the illusion that everything's just going to be hunky-dory work wise forever. I've never been under that illusion. Things could go away tomorrow"

This quote by Mel Gibson recommends that he is a realist and is not expecting his profession to stay successful permanently. He knows that his success could end at any moment and is gotten ready for that scenario. He is not under the illusion that his profession will remain effective indefinitely, and understands that things could change quickly. This quote reflects his humbleness and his understanding of the unforeseeable nature of the show business. He is not taking his success for granted and is prepared for the possibility that his profession might end at any time. This quote also reflects his durability and his ability to stay positive despite the unpredictability of his profession. He is not letting the fear of failure stop him from pursuing his dreams. Instead, he is embracing the unpredictability and is prepared to face whatever comes his method.
