Your first name of Sineada gives you a poised, gracious, and reserved nature. However, you have a dignity and poise that allow you to handle responsible positions in business. As you do not like to be taken for granted, you can be somewhat stubborn and unbending when you feel misunderstood. Because of your strong concentrative abilities, you can shut noises and activities out so completely that you may not even hear someone calling your name. You respect nature and the grandeur of the universe. You are intellectual and not easily swayed through the emotions. Your analytical qualities make you a good business head, capable and clever, and you could gravitate to executive, managerial, or accounting positions. As you live much of the time within your own thoughts, someone can be speaking to you face to face, but you will be thinking about something entirely different and have closed out the conversation. The mysteries of life appeal to you in your search for an understanding of the greater picture of life. Impromptu expression does not come easily unless you know your subject very well.
