I don't believe a return guarantees better fortune, even with a benefic planet like Jupiter. To me, a return marks a starting line, the fresh beginning of a planetary cycle. And when something new begins, I can't help but feel it's because something else has ended and endings are rarely simple or painless to walk through.
Twelve that’s when my family moved across the ocean to where we live now. A drastic change for a kid that age.
Twenty four I was just climbing out of a two year fog, a period where I had almost no luck finding worthwhile work. Looking back, I think that had more to do with my Saturn sitting in my 12th house.
Thirty six I weathered several painful breakups all within that same year. I mostly trace those back to Saturn’s transit through my 5th house.
