"I often quote myself. It adds spice to my conversation"

George Bernard Shaw's quote is a humorous method of revealing the concept that it is in some cases useful to draw on one's own experiences and concepts when talking. By quoting himself, Shaw is suggesting that he is able to bring a distinct viewpoint to the discussion, which can include a fascinating and entertaining component. This might be seen as a way of showing self-confidence in one's own ideas and opinions, along with a way of showing that a person is well-read and knowledgeable. It might also be translated as a way of revealing that a person is not scared to reveal their own ideas and viewpoints, even if they might be questionable or unpopular. Eventually, Shaw's quote is a reminder that it is important to be positive in one's own ideas and viewpoints, and to be willing to express them in conversation.
