Quote by Mike Tyson

"Discipline is doing what you hate to do, but nonetheless doing it like you love it."

"Fear is only in the mind."

"I'm the best ever. I'm the most brutal and vicious, and most ruthless champion there has ever been."

"You must believe in yourself when no one else does."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
