Received candidacy/ABD a year ago, after two years of courses and finishing a (qualifying?) paper in another year, so four years in. Years 1 and 2 were not great, but I managed. Year 3 was a ****ing nightmare, but they set the bar low enough for me to get candidacy. I thought it was a good idea to give it another year, but I was both unproductive and miserable -- aside from learning some Python, and scraping and cleaning a **** ton of NBA data. It's to the point where I spend over 90% of my waking hours avoiding work and other people entirely. Not good. Fortunately, I'm in a big city with lots of job opportunities, and I've already done some effective networking through some friends. I suspect I'll have a decent job by the end of the month. Since I have candidacy, I can always re-apply or apply elsewhere if I want to go back, and not have to re-do any coursework. Seems unlikely, although I still plan to play around with the basketball data I have.
