Career and motherhood will always tragically conflict.

Elizabeth Corey

I know from personal experience that this conflict in the soul does not go away, no matter how pleasant and accommodating our colleagues may be, or how flexible our schedules. We are limited, embodied creatures. These limits mean that we cannot do everything to its fullest extent at once, and certain things we may not be able to do at all. The tragic aspect of this is that both excellence and nurture are real, vital goods and that the full pursuit of one often, and perhaps inevitably, forecloses fully pursuing the other.
