i am too up to my neck in it to read through this thread, so sorry if i repeat anyone above.
i have a BA in English Honors and Film from Wayne State University in Detroit and an MA in the Humanities from the University of Chicago, and working on and earning both were incredible experiences that i value greatly. i am an adjunct professor at this point, and getting enough offers for classes between the two universities that i have been teaching at the past few years, that i actually had to turn classes down for the Fall 2021 semester.
i am also working on my PhD in "English," achieved candidacy almost two years ago, and honestly i am very disillusioned with things--luckily i love and believe in what i am researching and writing on in my dissertation though, so all of the other disciplinary and "professional" shit isn't discouraging me from seeing this through...i'm going to be sending my second chapter out to my committee in the next month or so, i am giddy to say...
...i'm not sure about how it works in other fields, but i can tell you that in the Humanities, take the time to make sure your committee can work together, because over the past few years it has become painfully clear that the two younger professors on my committee clearly hate the chair of my committee, and all of their petty, personal bullshit has come to the surface during my QE process and--especially--during my prospectus process...in fact, it took two different defenses of my prospectus, to get it approved, and in retrospect, i can see that the first attempt was totally a mess because of the issues amongst my committee members.
also, unfortunately the chair of my committee has been dealing with some serious professional issues the past year or two (had a kind of forced sabbatical and all because of them), and although he is incredibly committed to any students he works with, i see how it has gotten in the way at times. i owe him a lot, so i hate to complain--because of him, i had full funding to travel and research in Berlin for a week a couple of years ago, and likewise any of the conferences i've traveled to, but it has been a lesson on how much your committee's own lives and "careers" will impact your work.
ok, i just went back and skimmed through this thread and see that it was bumped for someone in the STEM fields (i think), but i'll go ahead and post this anyway...bottom line, like someone said above, you have to be about it to see it through, and you have to believe in the importance of the process and your work, at least close to as much as you do to what follows in your life after you have the degree.
best wishes to everyone in here, on what they're working on and pursuing!
