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."

"Hard work never killed anybody."

"Work with purpose and integrity."

"Hard work pays off in the end."

"A man's gotta do what a man's gotta do."
