Nick Fury (Age of Ultron)

"I've seen the best and worst of humanity. I still have faith in people."

"You think you know danger? Wait until you really understand it."

"I don't need your gratitude. I just need your commitment."

"The difference between success and failure is often just one decision."

"I've learned that the hardest battles are the ones against yourself."

"You want to make a difference? Then stop talking about it and do it."

"I don't have all the answers. But I know enough to keep us alive."

"The world's full of people trying to prove something. I'm past that."

"You have to be willing to fight for what matters. Always."

"I've commanded people from every walk of life. Character is what separates them."

"I'm here because when we needed him most, he didn't show up. But I'm not here to talk about the past."

"In my experience, there's no such thing as luck."

"The only thing we can count on is each other."

"Fear is a tool. Learn to use it."

"I didn't come here to sit and chat. I came here to finish what started."

"You want to know what I've learned? Nothing is certain."

"Power isn't just about strength. It's about will."

"We've all made mistakes. The question is what we do about them."

"I trust actions, not words."

"You think you can save the world? You can barely save yourselves."

"The world is changing. Either change with it or get left behind."

"I've seen good people do bad things when the stakes are high."

"Success isn't guaranteed. But giving up guarantees failure."

"You need to understand what you're fighting for, not just what you're fighting against."

"In this world, you learn quick or you don't survive."

"Time is the one thing none of us can get back."

"I don't believe in second chances. I believe in second efforts."

"A man without a plan is just a man with problems."

"You want my advice? Stop thinking and start acting."

"Strength comes from knowing your weaknesses."
