Sun-Moon Combination: Sun in Aquarius, Moon in Taurus (Sun in Aquarius, Moon in Taurus)
The combination of your Sun and Moon signs produces a personality that people find easy to like and admire. This is not so much for what you do as it is for what you don't do. Your never petty or small, and your appeal is to those in the higher as well as the lower rungs of society. You don't pester people with your worries and anxieties, but when others come to you, you drop everything to listen to their problems. You're interested in people, and like to be around them as an observer, but somehow maintaining a distance and not getting too involved individually. You rate people not on their position or rank, but simply on whether they interest you or not. You have a certain self-sufficiency about you, and you never feel that you have to put on airs to impress anyone. You have all it takes to be executive, except the desire that would be required. You seem to be devoid of any domineering or missionary spirit, willing to "live and let live." This combination blends the originality and independence of Aquarius, with the determination and powerful will of Taurus. These two fixed signs together give a will that is so strong that it may become obstinate and intransigent. Happiness can depend on assuring peacefulness and harmony in environment or home life, and in respect to human relationships. You need to be deeply interested in people

Your feelings may run deep, but you are not very likely to let them show. This birthday makes you a more private person, more introspective and perhaps more inflexible. In friendships you are very cautious and reserved. You are probably inventive, and given to unique approaches and solutions.

Sun-Moon Combination: Sun in Taurus, Moon in Aries / Taurus (Sun in Taurus, Moon in Taurus)
The combination of your Sun sign and your Moon sign amplifies the determination and purposeful nature of this sign of the Bull. Your concentration and staying power is second to none. Concentration is the base of your renowned tendency toward stubbornness, in that when you apply your mind to a subject, nothing is likely to distract your attention. Accordingly, you can focus with equal tenacity on your work, your domestic life, and your leisure activities. You are never one to jump to conclusions, but once you have made up your mind, you are never likely to modify your views. You are highly conventional, and you have a great regard for the establishment and the status quo. Change is something you prefer to avoid because you are slow to adjust and dislike being required to do so. You make a good friend because you are honest and loyal. You enjoy good friends, good food, good music, and in general, the "good life." You are materialistic, but with a special knack for saving and reinvesting. You are always a hard worker, and you don't mind starting at the bottom and slowly working your way to the top. You can achieve success because the work you do is done well and you are totally dependable. Patient and calm, your "tongue in cheek" diplomacy designed to humor opponents until, in the end, you have your own way. You respect authority simply because you expect someday to have it
