We all know the importance of saying "no." We've heard it time and time again, from our professors, mentors, and colleagues, and yet many of us still find it hard to do. Why does this happen? We're smart people, right? Why is it so hard to put into action what we know will work for us? In part, it's because the irregularity of our schedules makes it difficult to know how much time we actually have available. But I think there's another reason academics find saying "no" so hard. We’re programmed to please. We were the "good kids," most of us, the students at the top of the class. We were taught that being offered a responsibility was a good thing. When people ask us to do something, they affirm our sense of self-worth, particularly when they say something like "we thought you'd be good for this." Be careful when you hear that phrase! Make sure that you pause and evaluate the request, no matter how thrilling this
