My past self would be surprised by the following:

I am both less black and white and more black and white thinking than I used to be.
I no longer put as heavy of an emphasis on Science being the only way to explain things.
I have chosen to have less reliance on external validation.
I burned out and hit at least two rock bottoms, and still have not fully recovered from them.
I am pansexual and have at least grey thoughts about monogamy.
I am more spiritual.
I struggle socially (not in making friends, but how much anxiety or exhaustion I have around it)
I am disabled.
I can no longer travel or do physical activities that were a large part of my life.
Experiencing pain that is constant and chronic.
I would mourn so many things at such young an age.
My family would become disconnected.
I would have a much better relationship with my dad, but not my mom.
I would live in a non-high density or HCOL area.
I would consider a career outside of lawyer, psychiatrist, or scientist.
Difficulty reading or learning.
Commitment issues.
Losing some of my best friends or other partners.
I am neurodivergent (though that is only because the terminology did not exist at the time).
Not being able to solve all problems or get myself out of everything, a drop in self-reliance, see burnout.
Liking children and desiring to be a mentor or some sort of male au-pair.
No longer like drinking, but do enjoy cannabis, ketamine, and LSD.

My past self would not be surprised by:
Still a perfectionist
Still argumentative
Still a clown and silly
Enjoyment of philosophy and law
Holding out to not have a car for decades only to be saddled with a lemon.
Constant boredom and a need to know "why" or learn something new or otherwise seek out novelty and stimulation.
Don't know what to do in life. Want to be a constant traveler and learner.
Still hate cars.
Still have a pretension and elitist problem.
Struggle with self-love and self-worth, probably self-compassion too.
Overly generous.
Overly forgiving.
Lover of showers and baths.
Foodie despite hating the word and being anosmic. Becoming anosmic for two years and counting should be on the surprised list.
I learn best by visual instruction as well as hands on.

My current self, for the most part, likes itself in a way that I hadn't experienced for a long time. It's like my body took a break for ten years, deciding it hated itself and wanted constant improvement, all the while being its own worst critic and never really cheering it on. My current self is turning away from this mindset, and it feels great to have a more optimistic and self-satisfying life, but I just wish my physical body had not taken such a toll over the last few years.
