Your first name of Sieyen has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You work best alone and are happiest when expressing your many ideas creatively in an area that offers flexibility and challenge. The repression and frustration that you may experience at challenging moments in your life cause nervous indigestion and, in the worst cases, could result in ulcers and severe stomach problems. You tend to express yourself in an opinionated, candid, and matter-of-fact manner. If, for some reason, you cannot carry out your plans, you can experience deep moods of depression. This name gives the urge to leave home early in life. It gives you the desire to be a leader, to pioneer new undertakings, and to try new ideas in practical, creative occupations. You attend to tedious responsibilities only when you have no other alternative. You become intensely involved with everything you plan to do, but the stress arising from frustrating obstacles or misunderstandings with others could prompt you to be intolerant and sarcastic in your expression, with breakdowns in congenial relations with family and friends a possible end result. Intensity affects the senses of your head as well, whereby you could suffer with migraine headaches, sinus problems, or throat and swallowing difficulties.
