Quote by Severus Snape

"It is our choices that show what we truly are, far more than our abilities."

"Dunderheads. All of you. Particularly you, Potter."

"I can teach you how to bottle fame, brew glory, even put a stopper in death."

"One sip of this potion would make a man invincible."

"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."
