"My vanity is not remotely physical, it is cerebral. I suppose feeling self-conscious might be a form of vanity, though"

In this quote, Richard Griffiths is expressing that his vanity is not based on physical appearance, however rather on his intelligence and knowledge. He is recommending that feeling uncomfortable might be a type of vanity, as it is a way of being excessively concerned with one's own image. This could be interpreted as a way of being overly worried about how others view you, and how you view yourself. It is a way of being overly concerned with one's own self-image, and how it is presented to the world. This quote might be viewed as a tip to be conscious of how we present ourselves to the world, and to be knowledgeable about how our own self-image can affect our relationships with others. It is important to remember that our self-image is not based entirely on physical look, however rather on our intelligence, knowledge, and the method we provide ourselves to the world.
