The name of Rentaro has given you the desire for creative, artistic or musical expression in an original way. With increased familiarity you are inclined to speak your mind in a forthright, sometimes argumentative manner which creates annoyance and often hard feelings. You do not depend on others for encouragement, but you respond to appreciation and enjoy being the centre of attention. 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. You could be inventive and ingenious along practical lines. Because you like to get your own way, and your name makes it difficult for you to see things from other points of view, others accuse you of obstinacy or self-centredness. These tendencies could spoil long-term understanding and compatibility. However, once you make up your mind that something is going to work, you persevere until it is accomplished. In an argument, you usually emerge victor, but at a cost. Health weaknesses centre in the head with the use of this name: headcolds, sinus problems, headaches, or hay fever.
