Yup, both me, my recent ex, and our mutual friend who is his roomie now have the sag saturn square pisces jupiter.
Here's how it works on our example: Me, I know things will get worse before they will get better. I labor maybe seemingly slowly, taking little steps on several fronts to where I'm supposed to be getting, but I always get there. And I make sure that the nature of changes and lessons I am learning in the process are firmly in place, and are going to stay there. It may not be "fast enough" in the eyes of say, my parents or sometimes even a partner, but I am already attuned to this, and I know this is a road to success. True, there are extreme heights and lows in my life, but at this point I know nothing will kill me, and having all that plutonic force behind my butt, I do bank a lot on my phoenix-like qualities. But, the knowledge that I can indeed survive anything was painfully acquired. I should put all that mercury goodness I have to some use and write memories about my dramedylife one day
but I have come to terms with it. I definitely do try to side with the Saturn here, though sometimes it's hard to push myself to keep on going forward and not put things off more than I have to, in the end, it works out.
Then, my ex is doing the opposite, holding on to his Jupiter for dear life, and it has now come to bite him in the ***. Where I have been lucky in life, I saw it as that I tried to come forward to this result, and put myself in situations where good things can happen and worked towards it. He sees it as something that is just there and he is entitled to it. It's been there, it will be there, and it doesn't require effort on his part. where things start going sour, he banks on his eloquence to put things off, and continue his life of leisure and fun. He has been "given" many things and opportunities by his parents and other circumstances, but it has come to an end now, where he must put some effort for the first time ever into anything. He now has to support himself, finish his diploma work on a short time notice, and I wanted things off him to do in our relationship, in order to save it. He thought it's too much work, and he doesn't like to work on things, so it's over. Now he is seeing that silver tongue doesn't fix everything, and he must learn those Saturn lessons, that have been waiting for him there, and is basically a wreck, still yet to start doing anything about himself, while time is ticking.
The third person with the same set up has been more friendly with the Jupiter side also, and is in a similar situation to my ex, but he knows that the time for play and hedonism is over now and that he must deliver. So he delivers, fully realizing he has put himself into a situation with putting things off too and now something must be done about it. I think he is doing well to try to balance and harness the power of both of the planets, while living a drama filled life too, he is also trying to learn and not only play all the time like my ex. This guy is scorpio sun like me, and overall a fellow plutonian powerhouse, so our ways are very similar, both in terms of dealing with the drama the square brings and in terms of actually trying to learn and get down to the bottom of this. My ex in the middle example is a Sag sun, and overall has more sagittarian energy (even though there is quite a bit of plutonian undertones) and that is probably why he is more chummy with the Jupiter side of things, refusing to step off the ride and get down to business like me and his friend.
