My 2 cents: Get a Masters and go into industry. You will love the work you get to do in the field. Over time you'll learn what big unsolved problems are that we are currently facing. You might find one that particularly interests you and start thinking "man, I'd love to have a lot of time to really dig in and solve this problem, something my job never provides" Then you go back for the PhD where you get that time. The work ethic that you learned will be invaluable and you'll have something solid to pursue. In my opinion the two biggest wastes I saw when I was in my PhD program were: 1. most students had no work ethic. It was always "I fucked around all week and then rushed to do research before meeting with my professor" 2. not having any idea what kind of research the world needs. And why should you if you never go out and experience the world?
