In what promises to be the essential book on modern-day public speaking, top communication expert Amy Cuddy shares her tricks of the trade. She'll teach readers how to deliver their message effectively--whether they're speaking to an auditorium of thousands, to a small roomful of people, or one-on-one. Drawing on her experience as an Ivy League academic and keynote speaker, Cuddy shows that the secret to success for both introverts and extroverts lies in understanding your audience and, most importantly, yourself.
