You shouldn’t be a prisoner of your own ideas. Everyone gets into their own box and enunciates principles, if only in their own mind—you have your own constraints and your own structure that you think you’re following, and then you realize that what you’re saying is “I can do this, but I can’t do that.” And then at some point you say, “Well, why not?” and the answer is “Because I told myself I couldn’t.” If you keep telling yourself, “You can,” then you are liberated. If you’re totally constrained, all that’s left for you to do is break the mold. “Every wall is a door.”
