I am trying to come up with criteria to decide if I leave my job and start a PhD I was recently offered. One issue is the impact the PhD will have in my career: will it open new doors, will it make me a more attractive candidate to work for the government or the non-profit sector where I have been working for the past 10 years? Or should I just continue working on the issues I already have experience with and a network?
The main reason I am considering the offer is because I love the topic, I have been wondering about it for many many years and I would like to become an expert on it. It will be a big change for me, financially and geographically, as well as socially. PhD students can be very young these days.
