If this is based on salary, I am surprised to see psychology under least-regretted. I don’t see how a degree in psychology pays more than some of the majors under most-regretted.
My older one went straight to grad school so for her it’s hard to judge, but my other child is working before heading back to school. She was a biology major and would do it again. She makes a decent salary, has great benefits, getting excellent experience, etc.
I agree that you are who you are, and that most people will find their own success and be happy.
