Quote by Sun Tzu

"All warfare is based on deception."

"Know your enemy and know yourself."

"If you know the enemy and know yourself, you need not fear the result of a hundred battles."

"The supreme art of war is to subdue the enemy without fighting."

"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."
