I'm experiencing mine, more or less right now. I've been more or less knee-deep in the middle of altering the course of my life, and this is hard. However, I would also say that it is vastly preferable to the stasis of my previous life, because I do feel that I am moving forward ... albeit very slowly.
Like many people, I've been thinking very deeply about what I want my life to be, and I've realized how unhappy I was with it before. Many of the things that I thought I wanted before are no longer true.
I'm remaining optimistic, although it's pretty clear that absolutely nobody has a clue what to expect at this point, and especially with Uranus mucking things up (it's crossing my 4th house cusp and will do so several times).
What were you doing when you were 37?
Haven’t gotten there yet, but my mom moved far away from her region and family of origin, with her husband and children. I tend to think of her as always being strong, but I wonder if this was the beginning of her really cultivating the great strength I see in her. Less than a decade later, she had to make it on her own, and she did, and she got to retire this year. She laments the move in a lot of ways (SN in Cancer), but… NN in Capricorn.
My father was a first time father of a few months, traveling a lot for work when the NN was in Gemini and my Gemini stellium sibling was born, and then bought their first family home during his nodal return. NN in Taurus.
I got married to my best friend. NN in Libra.
There is some magic in that second Nodal return - it is close to the third Jupiter return and it is time to come off the SN and into life and the NN.
I started really looking after my health. Had left it all to luck previously. NN in Virgo.
I separated from the abusive husband and moved out. A very lonely time because no one cared. They thought I shouldn't have married the guy in the first place, so they didn't have much sympathy, although they never did argue against the marriage in the first place. NN in Pisces conjunct Ceres, 5th House. SN tightly conjunct Mars.
