Questioning and challenging our own thoughts and beliefs leads to better thoughts and beliefs. I feel that when I am being critical of myself and my beliefs (or when others are being critical of them), I am at my best because the world changes, evidence changes, and we change; everyone must have the ability to do this. When I feel like "I am this way or I believe this to be true," for a long period of time (which I do sometimes), then I feel stagnant and non-evolving.
