Quote by Black Widow (Age of Ultron)

"I've been red in the ledger. A lot of red. I'm not going to get it out."

"The hardest thing is living with yourself when you know what you've done."

"I know what it's like to have power forced upon you. It's not freedom."

"Everyone I've ever cared about has left. But I keep moving forward."

"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."
