Your first name of Cillian creates a serious, thoughtful nature, shrewd, efficient, and business-minded. It is sometimes challenging for you to listen to and understand the viewpoints of others because your opinions are strong, carefully thought out, and sensible. Being relaxed and spontaneous in social or formal situations is sometimes challenging, as you often value time on your own more highly. A tendency to be candid, combined with your diligence to look after the rights of people, can cause others to think of you as being interfering and bossy, or lacking in tact and understanding. Situations requiring sympathy and understanding, or where compliments are expected, may make you feel awkward and embarrassed. You prefer a simple, uncomplicated life where you can be original and ingenious in expressing your creative talents. You are one to make your own decisions, and not be influenced by others. By nature you are serious, thoughtful, and studious. In your personal relations with others, you are inclined to be rather serious, and not to see the humour others see, or to respond spontaneously. Your positive manner and outlook can make others feel that you are imposing your will on them and even interfering in their affairs.
