11. There is a psychological cost for quitting.

Just as there is a psychological cost to be paid for being a graduate student (see Reason 10), there is a cost to be paid for quitting a graduate program without a degree, or without the degree that you started out in the hope of completing. The causes of the discomfort are partly social: the pressure of explaining to others why you did not finish, the concern that others will perceive your not finishing as a failure, the expectations (real or preceived) of disappointed family members and loved ones, and the problem of explaining your foray through academe to potential employers. Other causes are internal, including disappointment with yourself for not completing something that you knew you were capable of completing.

The tragedy in this is that quitting may be the smart thing to do, but fear of the potential consequences can prevent you from doing so and prolong your time in graduate school, raising the psychological costs ever more. The longer that you devote to a program, the higher the cost of leaving can be, even if leaving is the best choice. Professor Timothy Burke of Swarthmore College has colorfully described this phenomenon. And for some of those who do successfully make their escape from graduate school, feelings of regret and incompletion can linger, irrationally burdening even people who go on to successful careers far from the Ivory Tower.
