I'm less than a month into a PhD in theoretical physics and am already seriously wondering whether it's right for me. Any advice would be hugely appreciated. Here are my (hopefully relevant) thoughts... apologies in advance for the length :) - It's very difficult to stay motivated to focus on research 8 or more hours a day, every day. I know I'll be taking courses come fall, which will break this up some, but I suspect when courses are done, it will be all research all the time until I'm finished with the PhD. - I love math & physics and ultimately want to teach at the college level (but not do research). I know adjunct & community college salaries tend to be dismal, but I also understand that it's next to impossible to get a decent full-time teaching position without the doctorate. I don't want to move around a bunch, either (which I understand is necessary as a postdoc). - I'm pretty sure that I'm not looking for a tenure-track position. The job security of tenure would be nice, but endless proposals and publications aren't for me. I just want to teach (but not live in near-poverty while doing so). - I have a Master's degree already. I had to take a year off for personal reasons before starting the PhD and was unable to get a job during that time, so no employment experience either. I do have 1 year of teaching experience at the school where I got my Master's. As a result of the time off, I feel like I've changed a lot and forgotten many things, and it's very difficult to get back into the routine -- even though I loved school and did extremely well as an undergrad/MS student. - It's also my first time living far away from home, so homesickness may be a contributing factor, and I certainly don't want to make a career decision based on that. What should I do? I want to teach college-level and earn a decent living (though I don't care about amassing wealth). I'm not sure that I can do computational research all day, every day for the next 3-5 years, though. I have no interest in experiment or industry. But, given that it's so very early in the PhD, I'm not convinced that I should just walk away... Would colleges even consider hiring me to teach, after a year of unemployment and an uncompleted PhD? I don't want to come across as unreliable. I should add that I like my advisor and the general atmosphere just fine. I've got undergrad loans to pay back, too, so finances are a concern there.
