An anecdote is not a datapoint, but I left my PhD because I saw the pyramid scheme and that I didn't want (or even could) maintain the effort required to climb up the pyramid. Now I'm a research assistant, I still do science but I no longer face the insane pressure of academia.

More generously, the people giving you advice are self-selected from the group of people who succeeded by taking that advice. I expect that the faculty are well-meaning, but perhaps not able to accurately gauge what will work for others.

I my world I have not met people who can accurately gauge what will work for others.

Even your peers in study might create pressure that having phd is something cool. I dropped my masters because I had job opportunity, some of my friends assume that I finished masters and that is why I have good job. Then I clarify, I did not finish it and they are somewhat disappointed.

I recall during undergrad that the stated goal of the professors was to 'unteach' us everything we learned in high school, and twenty years later I was thankfully finally able to unlearn everything I learned in undergrad. People that stay in a cult are unlikely to be fully honest with themselves and others about its shortcomings.

Graduate school was a non-issue as I went through that as a means to an end and virtually all of the professors weren't wrapped up in academia.

What were you studying? How do you know that your professors were wrong (that what they taught should be unlearned)?

Undergraduate in Art, I think they were right to unteach us what we learned in high school but that they were wrong in only teaching Art as it relates to the 'Art world' and that bias is a result of how colleges/universities hire Art professors.
