John Cena said this quote

I’ve often said a man’s character is not judged after he celebrates a victory, but by what he does when his back is against the wall. So no matter how great the setback, how severe the failure, you never give up.

~ John Cena

This is kind of hard to understand, but sometimes you can try so hard at something.Sometimes you can be so prepared, and still fail.

~ John Cena

Be loyal to those who are loyal to you. And respect everyone, even your enemies and competition.

~ John Cena

I'm the one person who wears the words 'hustle, loyalty, respect' on my T-shirts and merchandise. My audience is children. It's very flattering to see a kid wear your T-shirt; it's even more flattering to have a dad come up to you and say, 'I watch you with my kid. Keep doing what you're doing. You're a role model for my son.'

~ John Cena
