Sun in Capricorn in the 3rd House

You are much more serious than others your age. On the one hand, you like being taken seriously and enjoy having responsibility, but on the other hand you see that other young people aren't saddled with such responsibilities, and you tend to envy them.
You may develop a rather odd and unusual sense of humor. Through jokes and humor, you show that you recognize the seriousness of life, but you also escape from its overwhelming effects.
When you grow up, you want to be important and achieve something real that everyone can point to as yours. You are ambitious in everything you do and will work very hard to excel over others.
You are very practical and always ask what good something is.

Capricorn is a feet-on-the-ground, eye-on-the-prize sign. Those with Sun in Capricorn have a realistic, grounded approach to life that can be seen no matter how dreamy the rest of the birth chart suggests. These people know how to do things, and to get things done.
Some Capricorns naturally turn their backs on things they deem too frivolous. They are very much concerned with things that are worthwhile—and that includes their own lives. Capricorns want to do and be something worthwhile. Like their Earth signs relatives, Taurus and Virgo, they need to feel useful and effective in the real world in order to be satisfied with their lives. But the Capricorn spin on the earth signs is that Capricorn possesses a stronger need for recognition in a worldly sense. They have a strong sense of society and its framework, and they feel most secure when they feel they are doing their part within that framework.
Capricorns like to pare things down, and take pleasure in the simple things in life. However, many are attracted to status symbols and these ones will wear the best clothes (tasteful ones!) and drive quietly impressive cars.
Comparing Capricorns to their symbol, the goat, brings up some interesting analogies. Solar Capricorns can see into the future, and plan for it. They don't mind taking things slowly, but they absolutely aim to get to the top of the mountain in life! They make their way steadily and sure-footedly; and their strength and singleness of purpose are admirable.
Capricorns can sometimes be rather lonely people, although they rarely let it show. They are often a little reserved—even standoffish. This is generally because they value all things practical, and they'll seldom wear their emotions on their sleeves, unless they have a particularly flamboyant Moon sign.
This is a sign that is surely the most resourceful of the zodiac. To some, Capricorns come across as unimaginative, but they can be enormously creative when it comes to the material world. They are generally very capable people with a strong sense of tradition and responsibility.
Many Capricorns have mastered the art of making people laugh. Their sense of humor can be of the deadpan variety—they're generally excellent at keeping a straight face. They can be bitingly sarcastic, too.
Capricorns are not known for taking too many risks in life. They value the beaten track and things "tried and true". This is not to say they are stick-in-the-muds — they simply value the hard work laid down by those who've been around before them.
Turn to your Capricorn friends for help when you need to really get things done. They'll have practical advice, and they'll help you organize and manage your life a little better. Capricorns are generally good with their "word", dependable, and rather loyal people.

Sun in the Third House
Your mind is active, quick and quite curious. You are fond of talking and asking questions, although you sometimes speak when you have nothing to say. The more you can see and experience, the happier you are.
Your curiosity and your quick mind will help you in school, but you will have to learn to discipline yourself.
When you are older, communications may be an important part of your career.
You like to match wits with others, as in arguments, both friendly or unfriendly, and in word games or puzzle solving.

Sun Conjunct Venus
You have the ability to make others like you. When you want, you can be very agreeable and charming and can even win enemies over to your side simply by being friendly. And this is not just appearance; you are truly a very affectionate person who enjoys giving and receiving love.
It is almost too easy for you to find your way through life by being friendly and warm. At times it is necessary to confront people directly and forcefully; otherwise people may not take you seriously, or they may try to walk all over you.
You are fond of beautiful things and may have some ability in the arts. At the least you will appreciate the arts and will be able to make artistic judgments without relying on the opinions of others.
Sun Opposition Midheaven
You are very concerned with your inner personal world and less influenced by others' ideals and expectations than most people.
You are not principally concerned with achieving anything that others would consider great or significant. For you, it is important to have your personal world - your home, parents and family - operating smoothly.
You need a more secure and stable home life than most. Without it, your self-confidence and ability to be independent will be severely hampered.
Self-esteem is more important to you than the esteem of others.

Sun Sextile Mars
You have a great deal of physical energy as well as a vigorous mind. Everything that you do, you do positively and assertively without any great effort.
You have a strong sense of fairness and justice, and you will stand up for what you believe. If a friend is unjustly attacked, you will defend him. In a way, you regard your friends as being part of you, so that an attack on them is an attack on you, to which you react accordingly. For this reason you are a good team worker and player, although you can work by yourself if need be.
You have good health and need to be active. Try to engage in some physical activity as often as possible.
