Your first name of Grethen has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You tend to express yourself in an opinionated, candid, and matter-of-fact manner. You rebel at restrictions and are resourceful in unexpected circumstances. Lavish displays of emotion tend to embarrass you, making you feel self-conscious and inadequate. You appreciate nature and the freedom associated with being in a natural environment. This name gives the urge to leave home early in life. 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. Exploring new areas on your own, or with a few close friends, holds definite appeal and offers a constructive outlet for your restless energy. While you are creative, inventive, and ingenious in practical matters, and always ready to initiate and promote new undertakings, you often experience difficulty in bringing your undertakings to a successful conclusion because of your own changing interests or changing circumstances. Intensity affects the senses of your head as well, whereby you could suffer with migraine headaches, sinus problems, or throat and swallowing difficulties.
