Herminia Ibarra presents a model for career reinvention that flies in the face of everything we've learned from "career experts"—and is tailor-made for changing careers in today's uncertain world. Career transition is not a linear path toward some predetermined identity, according to Ibarra, but a crooked journey along which we try on a host of "possible selves" we might become. Successful reinvention comes not from deciphering and analyzing our past, but from inventing and testing our possible futures.
