Also I have always lacked a sence of direction.....I have no idea what I want to do with my life. Seems as if I have just been floating around, since as long as I can remember. It's not that I'm even disappointed in myself, or with my life..... Just seems that I should be doing more with it. Any help, advice or ideas concerning my chart would be appreciated. Thank you.
I think that others have pointed out the causes for your lack of direction and floating well enough, but there's a positive, flip-side to such placements too which can be actualized when you become aware and apply yourself consciously!
Your essential purpose is reflected by your Libra Sun and that's to bring harmony and balance to whatever you deem important -it's focused in the house of relationships, but will naturally be applied to everything else too.
Your MidHeaven (MC) is the cusp of the career house and concerns your worldly purpose. The basic theme of Sagittarius is expansion -from that of the mind and spirit to actually exploring the world. This doesn't mean that you need to travel (unless you feel called from within to do so) and I know one gal with a Sag. MC who isn't interested in that at all and she wishes to take classes and teach.
Uranus is the highest planet on the chart and right atop the MC so it suggests an occupation that is independent, different, unique, and perhaps innovative, inventive, intuitive or metaphysical in some way. Uranus is also the planet of astrology, so perhaps becoming an astrologer is an option. [I have Uranus on my Libra MC and I incorporated astrology into what I do.]
Your Moon-Neptune conjunction probably gives you some compassion, empathic and psychic sensitivity which are gifts that should be applied to a career in some way because these are in the 10th house. The Capricorn influence may wish to repress, control, or censor inner feelings and messages, but you can learn to trust those signals by going within, doing inner work like hypnosis and meditation more often.
The ruler of your MC is Jupiter which is in the 12th house of karma, subconscious mind and collective consciousness -a very psychic house, as well as a humanitarian house, but it is also conjunct your Ascendant so the worldly purpose of the MidHeaven can be carried out by tapping universal forces and accessing information about others psychically through the 12th, and through how you express yourself to others -which is your sensitive Pisces ASC.
Jupiter and Neptune are the traditional and modern co-rulers of Pisces so these are your chart rulers and very important and interlinked to this picture. Jupiter in the 12th is a very fortunate placement -a kind of "guardian angel" that typically saves one at the last minute or gets you out of sticky situations. But the 12th is also the Piscean house and most placements therein often cause some "blurriness" because they pick up everything like a radio receiver until you learn to focus and attune the mind, to clear the static and find your "station". Regular meditation and some time alone in solitude help one to do this, to gain or restore clarity.
So the Pisces, 12th house, and Neptune elements are (of course) all related, and point to a spiritual theme in your vocation. You could be a spiritual counselor who uses astrology and your inner senses specializing in relationship counseling -thus bringing the solar purpose back into the equation.
The South Node in Libra is the past-life marker and represents what is comfortable, but out-moded and stagnant. In Libra it usually represents a lifetime defined by relationship and may involve patterns of unheathy self-sacrificing behavior, dependence/ co-dependence, in the 8th house, possibly a reliance on someone else's resources, and ruled by Scorpion Venus its characterized further by control, manipulation, clinginess, obsession and/or jealousy. Any problematic "residue" from that life is solved by consciously pursuing the opposite node with some kind of self-developmental efforts.
So a third purpose in your chart is reflected by the North Lunar Node in Aries and applying to matters of the 2nd house, and this is a marker which tells you where your maximum soul growth and evolution lies. It would be helpful for you to develop positive Arian traits of healthy, psychological independence, self-confidence, and decisive action, and apply these to your values and self-worth. This is the house of money too so pursuit of financial independence and self-reliance could be part of it. The ruler of this node is your Mars so this purpose can also be carried out through Aquarian (humanitarian maybe?) approach to your goals and aspirations as well as involvement in groups, organizations and friendships in the 11th house.
