During my first week as a graduate student, I was inundated with resources from about a week of orientation sessions. Among the stacks of papers that I accumulated that week was a hardcopy of this mentoring guide published by Rackham. I remember thinking it looked potentially useful and briefly thumbing through it. But instead of being closely studied, the guide ended up in the middle of a stack of other papers which I had accrued at the same time, and my busy grad student life went on. As a burgeoning Ph.D. student, I had no concept of the real importance of good mentorship.
