Third, feeling like an impostor can make us better learners. Having some doubts about our knowledge and skills takes us off a pedestal, encouraging us to seek out insights from others.

This book is an invitation to let go of knowledge and opinions that are no longer serving you well, and to anchor your sense of self in flexibility rather than consistency.
