In the field I plan to work in, I will be making more than $100k/year, so ideally I would work while doing the PhD and tie the two together somehow. However, if that's not possible, I could see myself being a full time PhD student but doing consulting type work on the side since my hourly rate would be $50/hr or more. Even during my MS degree, it was common for me to do gig data work where I would get paid $2000 for 15hrs of work, stuff like that.
For me, I feel like I want the PhD mainly because I just want to learn and do more. It's not really about the title so much, though almost all of my closest friends have PhDs in hard STEM, stuff like engineering, chemistry, etc. One has told me for years I should do it, but I had other things going on. I feel like I want to work a few years to make money and gain experience so that I have a better understanding of how my PhD work will tie in with the real world, and I figure I'll be better suited to come up with research ideas if I work first too.
I appreciate the responses.
