Thank you for this!
makes sense. I feel like I’m being pulled in so many different directions!
No wonder: nearly everything in your chart, including both luminaries and the AC and all the personal planets, is in Sagittarius. That's the sign that can't sit still and is always going in multiple directions. Sagittarius's purpose is to explore, experience, and expand. In whichever way catches your fancy.
Anything else is useful to you only if it gives you the means to explore and experience more. If you achieved an undergraduate degree, it's not because the achievement itself mattered to you, but because it was the natural outcome of time spent studying, which probably did meet your need to experience and explore.
Or perhaps, if there came a time when studying did not feel fulfilling in that way, you sucked it up and finished because finishing would let you move on to more experiences. But you couldn't have done that if there was very much of a slog to get through. If you started to lose interest in the actual studies when you only had a couple of classes left, maybe you could manage that, but you wouldn't have been motivated if it was a whole other year. Either way, the degree itself wasn't the point.
If you go to graduate school, the degree won't be the point then, either. To stay motivated, you'll have to be enjoying the process itself. If you're not, if you just see graduate school as a hoop you have to jump through, you won't be able to stick with it.
You're not just a triple Sagittarius (sun, moon, and rising), but a Sagittarius powerhouse. Sagittarius on steroids. You're as close as it gets to being entirely, purely a Sagittarius. Most people with Sagittarius placements also have multiple other signs highlighted, which can bring in some very different energies, and make those other things equally important to them.
Sagittarius with Capricorn would have some need for achievement as well. Sagittarius with Virgo would agree on needing to enjoy the process, but while Sag just cares about the experience itself, Virgo is motivated by working out the details, and perhaps by pride in their work. Sagittarius with Aquarius or Libra would combine the desire for experience with a humanitarian mission statement (Aquarius) or desire to create beauty (Libra). Sagittarius with Taurus would need rootedness and stability as much as the joy of experiencing things.
But all you have outside of Sagittarius is Uranus and Neptune in Capricorn (which could trigger some achievement motive, although Uranus and Neptune don't achieve in the usual way, so I don't think they would help you through grad school if it doesn't meet your Sagittarian needs), and, very crucially, Saturn in Pisces squaring the later half of that Sagittarius stellium. Saturn is, for all practical purposes, your lone outside voice, and from 2014/15 to almost the end of 2017, it was transiting all your Sag placements. That's probably what gave you the ability to settle down and focus on college. Without a Saturn transit at that time, I highly doubt you would've stuck with it. Saturn is what gives us the ability to persevere and stick to something.
I am speaking somewhat from experience here: I have a Sagittarius moon, and Saturn was sitting on it when I started a three year herbalism program (finished last December). All my life, I've usually not wanted to commit to anything long term, because it felt like I was taking away the option of getting up and going somewhere. At that time, I actually was willing to commit to staying put for at least three years.
But now, you don't have Saturn keeping you in place. That's going to make it a lot harder to commit and a lot harder to follow through on anything, at least until Saturn moves into Aquarius and starts aspecting Sag again. Possibly, your natal Saturn square helps you somewhat with commitment, but without transiting Saturn touching your Sag placements, you're not going to be as motivated to buckle down.
To stay motivated for anything, whether it's school or a job or what, you have to be doing something that meets your personal needs for experiences that you enjoy and grow from. If you're not, it won't work, even if it's something that fits the general meaning of Sagittarius. Universities are considered Sagittarian, but pure Sagittarius is really the type to love learning but hate school. Foreign affairs are considered Sagittarian, but working in foreign affairs tends to mean plenty of boring meetings, which pure Sagittarius can't stand. Journalism may or may not really be Sagittarian, depending on what you're actually doing. Running around chasing leads, yes. Methodically checking off your leads, no. Working on an interesting story, yes. Proofreading or boring meetings, no way.
Would you be able to tell me what having these planets in the 1st house could indicate? I can never seem to find much about 1st house and career.
The first house isn't a career house. If someone has the sun, moon, and/or many planets in the sixth or tenth, which are the work and career houses, then the career area of their life is more crucial. They'll probably see a lot of personal growth related to their day-to-day work (sixth house) or their long-term career or being in the spotlight (tenth). In those cases, having the right career, matching it to their sun or moon or planetary message, is especially vital.
For people who don't have those houses highlighted, work and career are not always as vital. They might be able to just have a job, not necessarily one that relates to their personal growth path, and meet their personal growth needs in other areas of their life. However, the sixth and tenth house rulers also have a say in how one needs work and career to go, especially if there are no planets in the sixth or tenth house, so we need to consider the placements of the ruling planets, too.
For you, the first house is the main personal growth area of your life. That means that, whatever you do, whatever you have, you need it to be by and for yourself. With it all in Sagittarius, you need those Sagittarian experiences for yourself. You don't necessarily need to share them with others, and you don't really need others to bring them to you. You just go out and find those Sagittarian experiences for yourself. If you do share those experiences with others, that doesn't make them more fulfilling to you than having them on your own. (In contrast, if you had a lot of Sagittarius in the seventh house, which is other people, your Sagittarian experiences would require the presence of others, or at least you would find them more fulfilling when shared.)
Since the first house and that one sign also contains the rulers of your sixth and tenth houses, you do need your work to fulfill your Sagittarian needs. Which comes back to the "by and for yourself" message of the first house. But, because by and for yourself is how you're living your life anyway, nothing changes in that respect when it comes to career.
