Boss Up/Bake Bread, Jess Flanigan

Jepson School of Leadership Studies articles, book chapters and other publications

Taylor Swift’s “Wi$h Li$t” describes people who “want it all.” There, she declares that, in contrast to those who want it all, she dreams about living a quiet life with a driveway and a basketball hoop. This chapter argues that dreaming about a driveway with a basketball hoop while staying married to the hustle is still a form of wanting it all. Like Swift, and me, many other women today enjoy a degree of autonomy and material abundance that our grandmothers could only dream about. We’re free to boss up or settle down. But still, we have to make trade-offs. …
