Your first name of Siera creates a quick, clever mind capable of grasping and assimilating new ideas. You crave friendship, understanding, love, and affection but your reserved manner appears forbidding to others. Although you are very knowledgeable and intelligent, you often find spontaneous verbal expression difficult. You tend to be studious, analysing each new idea before accepting it. You can give expression to your personal thoughts and feelings most fluently through the written word. For your interest to be retained you need to be mentally challenged; this was most evident when young and in school. You work best on your own in fields such as with the products of the earth, real estate, or computer sciences, as long as you have the freedom to make your own decisions. You have a sensitive nature--sensitive to your environment and particularly sensitive to how your deeper and more serious interests are regarded by others. Health problems revolve primarily around worry and a weakness in the respiratory area that could lead to problems with the heart, lungs, or bronchial organs. Your sensitivity and lack of verbal expression frustrate and limit the satisfaction in life to be gained from your responsible and capable nature.
