I am willing to give up a high paying salary to return back to school as a PhD student and I am not tied down with a mortgage or anything else.
I find mathematics simply too interesting to not learn at the highest level. Working in industry will simply not teach me the material I want to learn. I’m considering going back for either a PhD in Math or a math heavy PhD in CS. I read math textbooks for fun and worked with tutors to ensure my proofs are done correctly. I can do this for hours on end without external motivation. I taught myself a lot of math and can see myself doing this as a career. I want to do research.
Most people my age say the same things in the comment sections in this thread (tied down to a mortgage, make too much money to return). I’m glad generalizations like these don’t apply to me and can’t wait to get back to school
