"I never thought that I was very intelligent"

Marion Zimmer Bradley's quote speaks to the idea of self-doubt and the power of our own ideas. It suggests that we can be our own worst critics, and that we can be our own greatest barrier to success. It also talks to the concept that intelligence is subjective, and that we can be smart in different ways. It implies that we ought to not be too hard on ourselves, which we need to recognize our own strengths and weak points. It is a pointer that we must not compare ourselves to others, which we must focus on our own specific talents and capabilities. Eventually, it is a suggestion that we ought to respect ourselves and recognize our own worth.
