The name of Duc has given you the desire for creative, artistic or musical expression in an original way. You could be inventive and ingenious along practical lines. You do not depend on others for encouragement, but you respond to appreciation and enjoy being the centre of attention. You thrive on interacting with people when you can implement your original ideas. Although you are congenial in the early stages of friendships, it is not easy for you to maintain relaxed, harmonious relationships because, through increasing familiarity, you are inclined to lack patience, to be intolerant, and to speak your mind in a frank, argumentative, and occasionally hurtful manner. Although you meet new people easily, it is not easy for you to maintain a relaxed, harmonious relationship. These tendencies could spoil long-term understanding and compatibility. With increased familiarity you are inclined to speak your mind in a forthright, sometimes argumentative manner which creates annoyance and often hard feelings. At times when your expressive urges seem to be bottled up, you experience stress and react to others critically instead of handling situations in a relaxed, cheerful manner. In an argument, you usually emerge victor, but at a cost.
