Cal’s old pal has written a new book: The First Rule of Mastery: Stop Worry About What People Think of You. And he shows Cal how to stop wasting time doing just that. But that’s not all. The psychologist for Super Bowl and Olympic champions tells Cal to triple down on visualizing a successful future, and teaches him exercises to achieve what he visualizes. Great anecdotes on self-awareness, clarity and conviction. A treasure trove of advice.
