“I’m incredibly grateful for the overwhelming response to ‘Inner Excellence’ and for the impact it’s had on so many lives around the world,” Murphy said in a statement. "My mission has always been to help people unlock their full potential — not just in performance, but in life — and I’m excited to continue that journey.”
Brown, a star receiver for the Super Bowl champion Philadelphia Eagles, was seen flipping through "Inner Excellence" while on the sidelines during a playoff game against the Green Bay Packers in January. The once-obscure book soon topped Amazon's bestseller list.
Brown has praised Murphy's guidance because football is "90% mental and 10% physical for me." He shared a photo of the book on social media with several passages highlighted and underlined in yellow.
