[10] His first book, The Power of Eye Contact: Your Secret for Success in Business, Love, and Life, was published in 2010.
For this book, Ellsberg interviewed millionaires and billionaires who do not have college degrees (including Matt Mullenweg, Pink Floyd’s David Gilmour, Sean Parker, and Marc Ecko).
[15][non-primary source needed] Ellsberg is credited for inventing "eye-gazing parties," a craze in 2010 where participants stare deeply into each other's eyes and follow up if they feel they made a connection.
He claims to have "been that guy" before,[22] and encourages men to reflect on examples of boorish sexual behavior, such as the viral Cat Person story, which is written from the perspective of a twenty-year-old woman who goes on a date with a much older man and ends up having an unpleasant sexual experience that was consensual but unwanted.
Ellsberg has asked men to pledge to get a verbal or nonverbal yes before initiating any sexual encounter, and to slow down if there's ever doubt the other person wants to continue.
