I was admitted to a PhD program for this coming fall, but I've increasingly realized that I don't enjoy research. I actively dislike it, in fact. So obviously a PhD is not possible at this point in my life. My program does offer a coursework-only option for the MS, though, and since I enjoy learning physics I think that's a better path. Has anybody else been in this situation of dropping down before even starting the program? What was your motivation to do so and how did it work out for you? Would I be better off remaining in the PhD program, doing no research, and sliding out the back door with a terminal master's?
