Your first name of Keillen 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. Because of the restless qualities within your first name, it is very often difficult for you to find pleasure in ordinary congeniality. If, for some reason, you cannot carry out your plans, you can experience deep moods of depression. It gives you the desire to be a leader, to pioneer new undertakings, and to try new ideas in practical, creative occupations. Therefore, if anyone interferes with your activities or offers unsolicited advice, you are inclined to react defensively and express your feelings in a blunt and, at times, caustic manner. You attend to tedious responsibilities only when you have no other alternative. You expect a great deal of yourself and of others, and you are seldom satisfied with your accomplishments. 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.
