"I have this theory that, depending on your attitude, your life doesn't have to become this ridiculous charade that it seems so many people end up living"

This quote by Christian Bale talks to the idea that our lives are mostly figured out by our attitude. He recommends that if we have a positive mindset, our lives don't need to become a "ridiculous charade" like so many people's lives do. This indicates that if we have a lack of confidence, our lives can become a charade. This might mean that if we have a lack of confidence, we might wind up living a life that is not real to ourselves, or that we might end up living a life that is not satisfying. It might also indicate that if we have a negative attitude, we may wind up living a life that is full of drama and turmoil. Ultimately, this quote recommends that our mindset can have a big effect on the instructions of our lives, which if we have a favorable mindset, we can prevent living a life that is a "ridiculous charade".
