I would not have chosen my major, I would have pursued my passion ( which never felt like a viable career path) and just rode it out to a doctorate. Those who can’t do teach!!! And your still forever in the pursuit of learning on something your passionate about and teaching as you go!!! I am thinking of getting my act together to pass the GRE and go back to school but delving into the math again in my 40s has been a huge hang up! 😬 Honestly two majors and 5 years of University I don’t think I retained a lot that I still regurgitate today. My major was a waste!
