Humble Inquiry by Edgar H. Schein, is an incredible read. He battle the ongoing epidemic of pride and ego in our culture today.
Edgar takes a stand for humility in all kinds of leadership and in this book, he says that being inquisitive is a key to humble leadership. According to Schein, telling is much less effective than asking is.
I highly recomend this book for everyone, but espescially if you are a type A personality and in any leadership role. We could grow our influence in others lives if we apply the thoughts of this book to our lives.
