Quote by Walter Matthau

"The only way to deal with an unfree world is to become so absolutely free that very existence is an act of rebellion."

"Age is no barrier. It's a limitation you put on your mind."

"Entertain the thought, but don't marry it."

"I think the key to life is just persistence."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
