When I think about the mentors I've had over the course of my professional life, I feel very fortunate. Each has been unique, injecting his or her thoughts, experiences, and personal style into our mentoring relationship. As I reflect on time spent talking with, listening to, or emailing with each of my mentors, it seems like the role of mentor came quite naturally to them, an effortless act that engendered feelings of respect and gratitude on my part. So what's the secret? How can we take full advantage of the mentoring relationships we are currently in, either as mentor or trainee?
