45. Nice advisers can be worse.

If you suffer under a tyrranical adviser (see Reason 44) who expects you to meet high standards and strict deadlines, you may rise to the occasion, produce outstanding work, and graduate in a reasonable amount of time. Of course, what today counts as “reasonable” is a very long time (see Reason 4) and you may still find that there are no jobs waiting for you at the end of an arduous journey through graduate school (see Reason 8). Nonetheless, there is something to be said for advisers who push their students through the various stages of a graduate program and then push them out the door with a degree.

The sooner you finish, the better. Graduate school delays adulthood (see Reason 12) and the longer you devote to a degree, the longer you will be without a salary. And there are few things more discouraging than sinking years of your life into working toward a degree that you never finish (see Reason 11). Having an adviser who offers you maximum intellectual freedom while allowing you to work at your own pace is an advantage if you are exceptionally organized, disciplined, and focused. However, if you are not, that kind of generous leeway can be detrimental to your chances of finishing in a timely manner or finishing at all. People tend to be most productive when they have expectations to meet and a schedule to follow. Ironically, it is often the kindest advisers who are the most averse to imposing strict expectations on their students, leaving them to rely on their own far-too-often insufficient self-discipline.
