So right now I'm working a job that I dislike. Of course it's only temporary, the goal being to allow my wife to finish school and save up enough money in order to allow me to enter graduate school with a minimum amount of debt. Up until this point I was bound and determined to get a Ph.D in physics, I figured I have plenty of work ethic (I work around 80 hours a week as it is) and perspicacity to get me through. So despite some of the things that I've heard, I figured I would just figure out the whole "job thing" after I was done. However after reading articles like this one: link I've begun to rethink the whole endeavor entirely. My question is, with my current education (a bachelor's degree in physics) can I perhaps pursue graduate coursework in fields like statistics, computer science or engineering? I wouldn't mind doing some more undergraduate coursework if it meant future happiness and success . Like most everyone in physics forums, I love doing math and physics (I do it pretty much everyday), and I guess at this point just want to find a career in which I can solve difficult problems and/or possibly do a bit of research, etc... I would love to hear from people who have either gone down the Ph.D path and have some pearls of wisdom to share or people who have decided to change fields entirely and how they feel about it now.
