Jupiter in Capricorn in the 1st house would point to my worldly success (financially and in terms of social status-probably politics) if that's what I really want, but my Sun stands in opposition to my Jupiter, my Jupiter squares my Saturn (I was born on July 3rd, 1996), and my Mercury is also opposite my Jupiter.
I've not a single placement in House X, my Mercury is square my Midheaven and my Saturn is opposite my Midheaven. My sun's in the 7th house, which is a fairly weak position because I tend to compromise rather than have that go-getter attitude.
Sun Opposition Jupiter means that what I could be poised for directly conflicts with my core nature, both in terms of signs and in terms of houses. I LOATHE the things that my 1st house Jupiter in Capricorn represents. I am, at heart, a sensitive, peaceful, and complacent family-oriented guy.
Jupiter square Saturn means that I'll need to overcome many obstacles, and put in tremendous amounts of effort to make my Jupiter work, because the hard aspect with Saturn makes me lack persistent willpower when it comes to doing something related to making $$.
Mercury squaring my MC, and Saturn opposite my MC are also hindrances. I can be very indecisive when it comes to settling with a plan on what I want to do, I'm 22 and I barely have a clue. My MC is at 0.52 degrees Libra, which could possibly mean an active social / public life tied to the chosen field of work. Again, that runs contrary to the nature of my Mercury in Cancer because Cancer's homely, reserved, and tends to withdraw when caught in a mood. Saturn opposite my MC makes me too withdrawn and insecure to achieve any sort of success that would bring me into the "spotlight."
So there you go. I have a Capricorn Jupiter in my 1st house, but it stands in direct conflict with my Sun and Mercury in Cancer and my Saturn. My MC is also afflicted except a sextile to it by Pluto but that means nothing when it relates poorly with key planets like Mercury and Saturn. I've never been an ambitious person and it's really hard for me to just get on with something, I fear ambition and success as I'm afraid it will change the sensitive, watery Cancerian side of me and the conservative, held-back Saturn.
