I dropped out of a PhD program (my advisor was somewhat abusive), and now, two years after, I have a chance to go back to another school, to another continent to finish it.
Should I do it? I want to stay in research; I enjoy this field. I know: if you want responsibility, and greater choices in research, you must have a PhD. I'm not sure if I want to have my own lab, though, and anyway, it's about 1 out of 9 graduates who get to have their own tenured positions, so I don't know what the other 8 does.
So what are the other opportunities with a doctorate, if not a tenure? Where else can you use it? What else can you do with it? I need to ask as any people as I can before I decide to spend three more years of my life getting it.
