“With Elbow Greaseand the books to follow, I want to offer kids a fun and engaging way to learn about the power of ambition, dedication, and heart,” said Cena in a press release. “These concepts have been transformative in my life, from my childhood up to now, and it’s so important to me to pass the positivity on and help our youngest generation see that right mindset is key to achievement."
