You're 18, almost 19, and you listed lots of different possible careers, which are very different from each other and require very different kinds of education and training. It sounds like you're nowhere near ready to pick a career. I would guess you have little or no experience related to any of those fields, so no real sense of what it's like to work in them day to day.
If that's where you're at, this isn't the time to narrow down your options, this is the time to explore.
Have you just finished high school? Are you starting college right now? Or are you doing something else at the moment?
If you're just starting college, this is your chance to take introductory courses in whatever you think would be interesting. More likely than not, you'll figure out something that really interests you that way. If you're working, or doing something else, then you get to try out a few different things in the real world and see what works for you.
It looks like you have a great need to explore and try things before settling on anything, and to keep your options open even when you have settled on something. Like wilsontc said, moon in tenth often means changeable career. And with your sun in Sagittarius, trying things out and having experiences is likely to be your natural way of doing things. Sagittarius is all about exploring and having experiences. By itself, it doesn't care about achievements or degrees, just about the experience.
You have some other chart factors that would help you channel your Sagittarian desire to explore into achievement: a trine between your sun and Saturn, and Jupiter, your sun sign's ruler, in Capricorn in the sixth house. Saturn and Capricorn both bring self discipline, drive, and desire for achievement. Sixth house is about day to day work. With a concentration of planets in Capricorn in the sixth, you're likely to be very disciplined about your work and very achievement oriented there... as long as you're doing a kind of work that fits with those planets.
It looks like you have a strong drive for education, too--that's a recurring theme in your chart. Sagittarius, Jupiter, and the ninth house are all about education (also such things as travel and religion and philosophy and experiences)--and all of them are highlighted several times over: Jupiter in a grand trine, Sagittarius your sun sign, making a trine to the ninth house. And you have south node in the ninth house and north node in the third, which suggests some kind of learning as a key theme for your growth over your lifetime.
Do you have any interest in psychology? That looks like another possible career for you. Sun conjunct Pluto: you're likely to be deeply fascinated with the human mind and/or the dark side of things. And the north/south node indicators you have suggest delving deep into the psyche and the dark side of humanity.
