Quote by Walter White

"I am the one who knocks."

"You asked me if I was in the meth business or the money business. Neither. I'm in the empire business."

"A man provides. And he does it even when he's not appreciated or respected or loved."

"I did it for me. I liked it."

"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."
