@Mame,
I agree with Mame and Roberta and will add that we all have different brains.
I spent a lot of years wanting to be a doctor, and I enjoyed reading the history of medicine as an early teen and studying chemistry and zoology and so on in school. We also had low money as a family and I worked a lot of hours when I was at the university. Few women were admitted to any of the United States medical schools back in the very early sixties, the most usual number for the large majority of the schools being none.
But some women in some places did get into the schools, even before all the civil rights changes in the US in the mid and later sixties. I was very smart in some classes (biophysics/histology was one) and dumb as could be in a few others, and that dumbness wasn't all due to being tired.
Later the admission policies changed a great deal and near contemporary female pals were getting admitted to med and law schools. I wasn't envious, had moved on. I knew by then I'd never be a terrific surgeon (etc.) and started getting interested in art and architecture in after hours (night classes). I went back to school in those fields and excelled. Besides excelling, I was liking it all, no matter how hard I worked in the new fields, even when I was exhausted, I loved it all.
In retrospect, I should have paid attention when I liked drawing house plans at ten... but I didn't.
I'm not sorry I liked medicine first - having more than one interest in my lifetime makes my "world view" more expansive. But it turned out my brain was a happier match for my newer interests.
I also started out a pretty isolated and narrow minded young person, and by virtue of meeting people different than I was (the university was a shock, in a good way) and hearing how they thought, I got - gradually - a more encompassing view of what goes on with people.
I notice that you post about a strong bias about some people, and post about almost crippling envy of some others.
It's possible to snap out of that and think of yourself "in their shoes".
I recommend it.
